Briefing
The state meteorological agency Aemet and the Generalitat Valenciana have issued a yellow weather warning for the Litoral sur de Alicante area, still warning of short-lived, occasionally heavy showers and thunderstorms. The warnings apply on Friday, 18 September 2026, and are expected to remain in force on Saturday, 19 September 2026; for the affected coastal area, Aemet gives rainfall accumulations of up to 20 litres per square metre in one hour as the threshold. This means there is an increased risk of localised flooding, particularly on exposed stretches of coast, and of Aquaplaning.
Aemet and the Generalitat’s municipal emergency coordination centres stress that these may be localised, fast-changing events: thunderstorm cells usually form over a small area and can bring very high rainfall rates and strong gusts within a short time. In the affected areas, they advise Protección Civil and the local authorities advise people to avoid dips and underpasses, not to park vehicles in dry riverbeds, and to expect traffic disruption caused by aquaplaning.
Away from the Litoral sur de Alicante, more settled late-summer weather is expected over much of the Comunitat Valencia and most of Spain over the weekend; however, isolated cumulus clouds and localised showers cannot be ruled out in the Valencia region. Sea breezes and mesoscale bands of showers may affect the local distribution of rainfall, so Aemet does not rule out short-notice changes to warning levels.
Travellers and residents on the southern Costa Blanca are advised to keep up to date with official Aemet warnings and notices from the Generalitat Valenciana and Protección Civil. Yellow warning status does not signal severe weather across a wide area, but does indicate an increased risk of locally heavy rainfall and the resulting disruption to transport infrastructure and low-lying areas. Specific time periods and geographical boundaries may change during the day, so short-notice updates are authoritative.
