FRIDAY WEATHER: Heavy rain, storms, strong winds and hail in the Canary Islands
Persistent and heavy rain will dominate western and southern parts of the Canary Islands today, Friday, as Storm Therese continues to affect the archipelago, according to latest forecasts from the State Meteorological Agency (AEMET).
The unsettled conditions are expected to intensify later in the day, with thunderstorms and hail forecast in several areas. On Tenerife, more snow is expected above 2,000 metres, rising to around 2,500 metres by the afternoon. Strong winds will also be a significant feature, with gusts of up to 100 km/h possible in higher altitudes and exposed areas.
Rough Seas and Hazardous Coastal Conditions
At sea, conditions will deteriorate throughout the day. South-westerly winds of force 4 to 5 will strengthen to force 6 along north-west and south-east coasts, bringing increasingly rough seas. Overnight, winds may reach force 6 to 7, with very rough conditions developing.
A north-westerly swell of 3 to 5 metres is expected, accompanied by heavy showers and thunderstorms. In contrast, north-east coasts will see lighter, variable winds and slight seas.
Due to this water sports, boat trips, diving, and other sea-based activities or excursions will be cancelled in affected areas.
