The last few hours have been marked by a resurgence of atmospheric instability In the Dominican Republic, the situation has escalated to the point that the Emergency Operations Center (COE) has maintained a green alert level in several provinces, including the National District. The combination of a trough and a frontal system has triggered heightened vigilance due to the possibility of heavy downpours, strong winds, and flash floods.
This scenario has led emergency authorities and meteorological services to strengthen preventive warnings The alert level affects the population, especially in the eastern, northeastern, and northern regions of the country, as well as in coastal areas along the Atlantic. Although the alert level does not imply imminent damage, it does indicate a potential risk that requires continuous attention and some caution in daily activities.
Why has the green alert been declared and extended?
The triggering factor in this situation is a trough associated with a cold front which has been strengthening as it has moved over the region, interacting with warm, humid winds from the south and southeast. This combination favors the formation of clouds with significant vertical development and moderate to heavy downpours in large areas of the Dominican territory.
According to the most recent reports from National/Dominican Institute of Meteorology (Indomet)Cloudy skies and rain have been observed in eastern, southeastern, and northeastern provinces since early morning. Some areas have reported heavy rainfall. persistent rainfall which, although occasionally moderate, tend to be accompanied by isolated thunderstorms and gusts of wind.
This dynamic initially led the COE to declare green alert in five provinces From the east: La Altagracia, La Romana, El Seibo, San Pedro de MacorÃs, and Hato Mayor. However, as the trough and cold front have strengthened, the agency has decided raise the alert level to a total of 10 and later 11 districts, also including the National District.
According to bulletins released by the COE, the alert is justified by the expectation that these systems will continue to generate intense downpours in short periods of timeThis is a typical condition for episodes capable of causing urban flooding, sudden rises in rivers, streams and ravines, as well as landslides in vulnerable areas.
Meteorologists add that, in addition to the frontal component, there persists residual moisture over the country and a flow of wind from the north and northeast that brings cloudiness from the Atlantic, keeping the atmosphere unstable especially on the northern slope and mountainous areas.
Provinces affected by the green alert and areas with the most rainfall
The evolving situation has led to adjustments being made to the COE's surveillance map as weather conditions change. At the point of maximum extent, the agency placed... Green alert for eleven provinces and the National District, focusing attention on both the eastern strip and the northern coast and areas near Cibao.
Among the most frequently mentioned demarcations in the reports are La Altagracia, La Romana, El Seibo, San Pedro de MacorÃs and Hato Mayorwhich, since the beginning of the episode, have been under the direct influence of the trough associated with the front. These are in addition to Monte Plata, San Cristóbal, Santo Domingo, National District, Samaná and Puerto Plata, where significant cloud cover and recurring rain have also been observed.
Indomet has indicated that, during the morning, light to moderate downpours have been recorded in Santo Domingo, La Romana, San Pedro de MacorÃs, La Altagracia, Barahona, Pedernales, Azua, Peravia, San Cristóbal and San José de OcoaIn the afternoon and evening, these rains tend to intensify locally and extend into the provinces of Cibao and the southwest region.
Within the valley and the Central mountain range, weather reports record episodes of rain in La Vega, Monseñor Nouel, Santiago and Valverde, while on the Atlantic coast, municipalities of Puerto Plata, Espaillat, MarÃa Trinidad Sánchez, Samaná, Monte Cristi, Dajabón and Santiago RodrÃguezIn these territories, the orography favors the condensation of moisture and the appearance of persistent clouds.
The COE has made it clear that the list of provinces under green surveillance It's not staticDepending on whether rainfall decreases or increases, the institution may discontinue the alert level in some areas—as has happened at specific times with Puerto Plata or certain eastern provinces—or, on the contrary, maintain monitoring where the risk of significant accumulations persists.
How the rain and weather might evolve in the coming days
The prediction models used by Indomet point to a weather pattern marked by episodes of intermittent rain and gradual changes as the cold front moves on and a drier air mass settles in. However, while the trough remains active, showers are expected to continue at different times of day.
For afternoon and evening hours During the most unstable days, rainfall is expected to increase in intensity and extent, especially in parts of the Yuma and Higuamo regions and in the Cibao area. The downpours could be accompanied by isolated thunderstorms and gusty winds, with a higher incidence in areas of rugged terrain.
Overnight, forecasts indicate that the The most significant downpours will tend to concentrate towards the eastern and northern portions of the country, maintaining a scenario conducive to rapid rises in rivers, streams and ravines, as well as to flash floods or urban flooding in areas with poor drainage.
Looking at the short term, the bulletins indicate that, once the cold front moves away As a drier air mass begins to dominate, the probability of precipitation will gradually decrease. In that context, rainfall is expected to become more restricted to the Atlantic coast and parts of the Cibao Valley, with passing showers in the Central mountain range and the southwest region.
In subsequent days, a pattern of partly cloudy to occasionally cloudy skies would persist, with Light to moderate rain and occasional gusts in northern and northeastern provinces, while other areas of the country will enjoy intervals of sun and clouds without significant episodes of instability.
Impact on temperatures, fog and wind chill
In addition to the rain, the passage of the frontal system is accompanied by a noticeable drop in temperatures across much of the country. This cooling is most noticeable during the night and early morning, especially in mountainous areas and inland valleys where temperatures tend to fall below the usual average.
Meteorologists point out that the minimum temperatures Temperatures can range between 15°C and 18°C ​​in some higher-altitude locations, while highs will be around 23°C or 25°C in much of the country. These are slightly cooler than usual for this time of year, so it may feel a bit chilly for those living at higher elevations.
In municipalities located in the Central mountain range and its surroundings—such as Constanza and other intramontane valleys—the appearance of morning fogs and mistsThis phenomenon reduces visibility on roads and mountain passes. This situation requires both drivers and pedestrians traveling during the early hours of the day to exercise extreme caution.
In lower-altitude urban areas, the environment is described as pleasant to freshwith some relief from the colder temperatures compared to warmer periods. However, the sudden changes between day and night can affect vulnerable groups, such as children, the elderly, or those with respiratory illnesses, so it is recommended to dress warmly at night.
This scenario of more moderate temperatures combines with north and northeast winds, which not only bring cloud cover but also reinforces the feeling of freshnessespecially in coastal areas open to the Atlantic and on slopes exposed to the dominant flow.
Associated risks: floods, inundations and vulnerable areas
The main concern of the civil protection authorities and the COE is related to the side effects of the rainsmore than by their mere presence. Intense downpours in short periods can trigger flash floods in rivers, streams, and ravines, as well as urban flooding in neighborhoods with poor drainage or settlements built along waterways.
In the provinces under surveillance, the COE has warned of the possibility of cases being registered localized overflows In low-lying areas and communities near waterways, especially in areas where soil moisture has already accumulated. This risk increases in the eastern region and in parts of the north and northeast where rainfall may persist for several hours.
The regions Yuma and HiguamoThese areas, cited in some weather reports, are among those likely to experience moderate to heavy downpours accompanied by thunderstorms and gusts of wind, which adds an extra factor of danger in terms of falling branches, minor landslides, or occasional service interruptions.
In densely populated urban centers, such as Greater Santo Domingo and the National DistrictThe problem centers on water accumulation in streets, underpasses, and areas where the sewer system may be overwhelmed. Here, the authorities' emphasis is on preventing people from risking crossing flooded areas or traveling along roads with visible water currents.
It is also worth noting that the combination of gusty winds and saturated soils This can facilitate the falling of trees or poles in certain areas, which is why it is important to maintain vigilance in residential areas and report any risk situation to the relevant authorities.
Maritime conditions and navigation restrictions
One of the most sensitive aspects of this green alert situation has to do with the sea ​​state on the Atlantic coastThe COE and meteorological services have been particularly clear in recommending that fragile, small and medium-sized vessels remain in port in several sections of the northern coast.
The official notices specify that the recommendation covers everything from the From Manzanillo Bay, in Monte Cristi, to Cabo Engaño, in La Altagraciaand in some bulletins it even extends to areas like Cabo Francés Viejo. All this is due to the presence of strong winds and a abnormal swell which significantly increase the risk to recreational boating and artisanal fishing.
For night on the north coastForecasts indicate a further increase in wave height, which could make the sea dangerous in exposed areas. For this reason, crews are urged not to venture out to sea and, in the case of strictly necessary operations, to limit themselves to the immediate vicinity of the coastal perimeter, closely following the instructions of the port authorities.
In contrast, in the caribbean coast The swell has remained within more manageable parameters, allowing navigation with standard caution. Even so, the COE insists that prudence should be exercised and any updates to the bulletins that could modify this initial assessment should be respected.
The persistence of moderate winds with frequent gusts along the coast means that the sea can change state relatively quickly, which is why the authorities insist that the first reference The decision to go out to fish or not should always be based on official notices and not on momentary visual perception from the shore.
What does the green alert level mean and how should you act?
The COE defines the green alert This refers to the phase in which expectations of a phenomenon allow us to anticipate the possible occurrence of an event that could be dangerous to the population, either partially or completely. It is not the highest level of emergency, but it is a clear sign that we must be vigilant and prepared.
Among the most frequently repeated recommendations is that of Do not cross rivers, streams, or ravines Those with high water flow should avoid using spas located in the provinces under surveillance. Many of the victims in episodes of heavy rainfall occur precisely when the force of the water is underestimated in seemingly normal crossings.
The COE and relief agencies are asking residents in high-risk areas—such as riverbanks, unstable slopes, or neighborhoods in flood-prone areas—to take precautions. basic preventive measures, ranging from securing belongings and important documents to identifying evacuation routes and nearby shelters should the authorities order it.
To report any incident or request for help, institutions provide citizens with the usual emergency numbers, including the 911 and specific lines from the COE. The public is advised to stay in contact with Civil Defense, Armed Forces, Red Cross, National Police and fire departments, which make up the disaster response network.
Additionally, emphasis is placed on the importance of only follow official guidelines disseminated by the COE, Indomet and other competent bodies, avoiding the spread of rumors or unverified information that may generate confusion or unnecessary risk behaviors.
What weather is expected in the coming days and what room is there for improvement?
Looking ahead to the immediate days, Indomet's forecasts point to a gradual change in weather pattern As the cold front moves forward, leaving behind a drier and colder air mass, this process should result in a gradual reduction in the frequency and intensity of rainfall across much of the country.
In the short term, they are still being considered scattered showers on the Atlantic coast During the morning hours, the showers will affect provinces such as Puerto Plata, Espaillat, Hermanas Mirabal, MarÃa Trinidad Sánchez, and Samaná. Later in the afternoon, the showers will tend to move toward areas of the Cibao Valley, the Central Mountain Range, and the southwest, including locations such as Santiago, La Vega, Monseñor Nouel, Barahona, and Pedernales.
Looking ahead to the following days, meteorologists predict that the dominance of a mass of air with lower humidity This will favor more stable skies across large areas, although northeasterly winds could continue to generate periods of light rain along parts of the northern coast and in some inland areas. It is possible that, depending on this improvement, some green alert levels may be discontinued where the risk steadily decreases.
Even so, it is emphasized that citizens should maintain the monitoring of official bulletinsThe atmosphere can react differently than expected if the trough strengthens or if new frontal systems approach the region. Flexibility to adapt to last-minute changes is key in unstable weather scenarios.
Overall, the outlook points to a few days marked by intervals of clouds, occasional rain, and relatively cool temperatures, with a slow but reasonable trend towards stabilization, provided that the cold front continues its movement and no new pockets of intense instability emerge.
This whole episode of green alert declared and extended The COE's report illustrates the extent to which a frontal system and a trough can alter the weather in the Dominican Republic, generating intense rainfall, rough seas, and temperature drops in just a few hours. Although the most severe scenario is currently concentrated in the Caribbean, the dynamics of these types of warnings and the coordination between meteorology and civil protection also serve as a reference for other environments, including the European sphere, where early warnings and responsible citizen response make all the difference in minimizing damage when the atmosphere becomes complicated.
