Mallorca faces another weather hazard

Mallorca is on high alert as well, due to the risk of flooding that thunderstorms and heavy downpours pose in some areas. This warning is especially important for those who plan to travel on the island. Roads can quickly become dangerous when heavy rain falls in a short time.

Mallorca has been hit by a severe weather spell this month. On September 9, emergency services in Mallorca dealt with 185 cases after strong winds and heavy rains. The island also experienced flooding.

Thursday, 17th September, is now receiving special attention. Predictions point to a potential severe combination of thunderstorms and flooding on Mallorca.

Take care of the road!

If you are travelling in heavy rain, avoid driving on flooded roads. Never drive through water that is not clear.

Even if a road seems passable, cars can quickly lose their grip in standing water. Fast-moving floodwater is also dangerous. The people living in the affected area should also remove loose items from terraces and balconies, check gutters and drains, and be aware of local warnings.

AEMET says its Meteoalerta system This app gives you the latest information on dangerous weather in Spain, up to 72-hours ahead. Conditions and warning levels may change with each update.
