Heavy rain and thunderstorms are forecast for the Balearic Islands, Canary Islands and parts of northeast and eastern mainland Spain until at least September 25. and across the Balearic Islands at the end of September 24-25. Thunderstorms are expected to break out in parts of the autonomous communities of Aragon, Catalonia and Valencia on September 23 and 24, as well as in the Balearic Islands on September 24 and 25. Thunderstorms can be accompanied by strong gusts of wind, lightning and possible hailstorms. The Spanish State Meteorological Agency (AEMET) has also issued an alert notice regarding a tropical disturbance located between Cape Verde and the African coast which has a high probability of becoming a tropical cyclone in the coming days and is expected to bring heavy rain, strong winds and rough seas to the Canary Islands from September 24 to 26.

As of September 23, AEMET has issued the following weather warnings in the affected area:

  • Orange heavy rain warning (mid level on a three level scale): Northern and central parts of the Autonomous Community of Catalonia on September 23 and 24; parts of the Balearic Islands from September 24 to 25; and parts of the Canary Islands on September 25.

  • Orange thunderstorm warnings: Parts of the Balearic Islands on September 24 and 25 and parts of the Canary Islands on September 25.

  • Yellow heavy rain and thunderstorm warnings: Parts of north-central and southern Aragon, Catalonia and the autonomous communities of northern and central Valencia on September 23 and 24; through the Balearic Islands on September 24; and parts of the Canary Islands on September 24 and 25.

Authorities could update and possibly expand coverage of weather warnings over the next few days.

Dangerous conditions
Sustained heavy rains could trigger flooding in low-lying communities near rivers, streams and creeks. Urban flooding is also possible in developed areas where stormwater drainage systems are easily overwhelmed or lacking. Sites located downstream of large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where heavy rainfall has saturated the ground. Disruptions to electrical and telecommunications services are possible when major floods or landslides affect utility networks.

Floodwaters and debris flows can render some bridges, rail networks or roads impassable, impacting overland travel in and around affected areas. Puddling of road surfaces could lead to hazardous driving conditions on regional highways. Authorities may temporarily close some low roads that are inundated by floodwaters. Extreme weather conditions could also lead to flight delays and cancellations at regional airports. Flooding could block regional rail lines; freight and passenger train delays and cancellations are likely in areas that experience heavy rain and possible track flooding.

Localized business interruptions may occur in low areas; some businesses may not be operating at full capacity due to facility damage from flooding and the inability of some employees to get to job sites.


Monitor local media for weather updates and advisories. Confirm all transportation reservations and business arrangements before traveling to affected areas. Obtain up-to-date information on road conditions before driving or routing expeditions in areas where extreme weather conditions are expected; plan for possible supply chain disruptions in affected areas. Stay away from high streams, creeks and other waterways prone to flash flooding. Do not attempt to navigate flooded roads. Use caution in high terrain due to the threat of landslides, as well as in mountainous areas where avalanches pose a threat. Charge battery-powered devices during extended power outages.
