Event

Heavy rain and thunderstorms are forecast for the Balearic Islands and parts of eastern mainland Spain until at least November 11. 12. Rainfall totals of about 4 cm (1.6 inches) per hour are possible in these areas. Thunderstorms are expected to erupt in parts of the Balearic Islands from November 10-11 and in coastal areas of eastern mainland Spain on November 11. Thunderstorms can be accompanied by strong gusts of wind, lightning and possible hailstorms.

The Spanish National Meteorological Agency (AEMET) issued the following weather warnings in the affected area on November 10:

  • Orange heavy rain warning (mid level on a three level scale): Through Mallorca in the Balearic Islands.

  • Yellow Heavy Rain Warnings: Central and southern coastal regions of the Autonomous Community of Valencia and southern and southeastern parts of the Autonomous Community of Murcia, as well as the rest of the Balearic Islands.

  • Yellow storm warnings: Through the Balearic Islands.

The following warnings were issued for November 11:

  • Orange heavy rain warning: In most of the northern and central coastal areas of the Autonomous Community of Valencia.

  • Yellow Heavy Rain Warnings: In most of the rest of the Autonomous Community of Valencia and the south and south-east of the Autonomous Community of Murcia, as well as in Formentera, Ibiza and Mallorca in the Balearic Islands.

  • Yellow storm warnings: In the coastal regions of the Autonomous Community of Valencia and the south and south-east of the Autonomous Community of Murcia.

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 rains have saturated the ground. Disruptions to electrical and telecommunications services are possible when major floods or landslides affect utility networks.

Transportation
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. Floods 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.

Tips

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.
