The Agencia Estatal de Meteorología (Aemet) has issued El Hierro a yellow weather warning for heavy rainfall. The warning is in force from 12.00 local time on Monday until 23.59 on Tuesday. At least 60 millimetres of rain in twelve hours are forecast, locally in the form of heavy showers that may be accompanied by thunderstorms.
The cause is continued instability associated with DANA Adam, a cut-off upper-level low that has affected large parts of Spain since the weekend. While higher warning levels apply to the east coast and the Balearic Islands, the Canary Islands remain under yellow warnings. Aemet stresses that yellow warnings indicate an increased but moderate risk: dangerous weather events may occur locally, but need not affect the whole area.
The authorities on El Hierro recommend avoiding exposed areas, not driving through low-lying areas and barrancos, and following guidance from the island administration. So far, there have been no publicly confirmed reports of serious damage or evacuations on the island. Any further measures will be decided in response to how the situation develops.
DANA Adam is also bringing significant weather events to mainland Spain and the Balearic Islands. On Monday, Aemet reported temporary red warning levels for very heavy rainfall in Alicante and Valencia In Barcelona, Ibiza, Mallorca and Menorca orange or yellow warnings were issued, which may shift and ease during the day. The heaviest rainfall is expected north of the Valencian coast and in parts of Catalonia in the afternoon, while El Hierro may see mainly prolonged rain with embedded thunderstorms.
For the Canary Islands, Aemet notes that warnings may be extended or adjusted in timing depending on the latest observations. Travellers and residents should follow short-term forecast updates and be prepared for changeable conditions. The next Aemet bulletins and notices from civil protection services on the islands will be authoritative.
The weather situation remains dynamic. Small-scale developments around the upper-level low will determine the intensity and distribution of the rainfall. Conditions are not expected to ease until the moist, unstable air mass moves away; Aemet will refine the timing over the coming hours.
