The powerful storm EfraÃn , named by the Portuguese meteorological agency IPMA, will affect not only neighboring countries but also Spain in various ways. It had previously been monitored by the National Hurricane Center and designated Invest 99L, an intense subtropical cyclone.
In this article we are going to tell you about the characteristics, origin and danger of the EfraÃn storm.
Origin and characteristics of the EfraÃn storm

Tropical Storm Ephraim originated from an active subtropical cyclone monitored by the NHC's National Hurricane Center a few days earlier. The NHC gave it a 50% chance of becoming a named subtropical storm , which would have been named Owen. It was only classified as Invest 99L when it was well southwest of the Azores. Although the storm brought very strong winds over a wide area of ​​open water, it did not develop into a subtropical storm.
A few days earlier, the powerful Invest 99L moved across the cold waters toward the Azores, losing some of its subtropical organization as it interacted with a polar trough that rapidly intensified into a powerful mid-latitude low. On its southern side, Ephraim is associated with a strong flow of atmospheric moisture and a belt of subtropical precipitation, which is expected to be redirected toward the Iberian Peninsula. This phenomenon is crucial for understanding the storm's characteristics and how it will develop in the coming days.
Farther north, a powerful blocking anticyclone prevented Efrain from moving naturally to higher latitudes. Most likely, the EfraÃn storm moves towards the Iberian Peninsula after sending a very effective rainfall band, a secondary low pressure trough separating from the mother storm, heavy seas, etc.
Impacts of the EfraÃn storm

Ephraim received the name of the storm due to the severe impact of strong winds, heavy rains and rough seas in the Azores. The storm will then move slowly across the North Atlantic and may move towards the peninsula in a weakened but somewhat active form.
Rain is guaranteed across most of Spain, especially along the Atlantic coast and in the southern part of the peninsula, where it could be very heavy. Note that the Ephraim low will remain almost unchanged until Wednesday the 14th, while bringing a band of precipitation and a secondary pressure system. The storm will approach in the second half of next week.
As mentioned above, EfraÃn has a river of strong atmospheric humidity, RAH, associated with its southern flank, accompanied by strong winds. It may later be related to the . When the deep storm is near the Azores, these rivers with bands of precipitation will retreat toward the .
Precipitation and storms
We will have fronts and associated rain due to these high-pressure systems . Storm Ephraim will be driven by a strong westerly flow and will gradually move towards the peninsula starting in the middle of next week, bringing heavy rain again.
In short, the powerful storm EfraÃn will join the carousel of storms and fronts that affect us these days and will bring us a new batch of rains, heavy seas and strong winds in the coming week.
