The Department of Citizen Security formalized by decree the entry into force of the PEMU, which entails the cancellation of sporting and cultural events and outdoor leisure from 08:00 a.m. on Saturday, August 9, as well as the suspension of the Sunday Rastro 10 for August.

Los access information panels They operate especially on weekends and holidays with good weather, in order to reduce queues and improve accessibility in this coastal enclave and gateway to the Anaga mountain range.
Advection fog: what it is and why it appeared in the capital
The morning left a advection fog image In Santa Cruz and points in the north of the island: a low layer that hid part of the skyline and caught the attention of those arriving to work.
This phenomenon originates when a mass of warmer, more humid air It slides over a colder surface, in this case the sea, and as it cools at its base condenses moisture, forming fog banks that can persist for several hours.
Aemet sources in the Canary Islands emphasize that It is not linked to the calima; the calima responds to the intrusion of warm air and suspended dust, while the advection fog is condensation of water vapor by thermal contrast and usually dissipates as the morning progresses.
Weather forecast and expected temperatures
The Aemet foresees maximum temperatures around 37ºC, with peaks that could reach 40ºC In Gran Canaria, the Canary Islands Government does not rule out local values of 41–44ºC in the interiors of Lanzarote, Fuerteventura, Gran Canaria and Tenerife.
At night they are expected high minimums in midlands and interiors, which can be located between 25 and 30ºC, which increases heat stress and requires strengthening personal protection measures and adequate rest conditions.
However, the City Council reiterates the call for caution: Follow official warnings, avoid risks in the natural environment, and plan trips to the coast in advance, checking traffic and parking occupancy to minimize waiting times.
