These three districts will be under warning between 12:00 and 18:00 today and then between 00:00 on Tuesday and 00:00 on Wednesday.
The IPMA also issued an orange warning for the entire Portuguese coast due to sea unrest and yellow for 14 districts due to rain, which could be heavy and accompanied by thunderstorms.
The bad weather forecast for the next few days led the National Emergency and Civil Protection Authority (ANEPC) to issue a warning to the population on Sunday, warning of the possibility of urban flooding, floods and landslides.
In the notice, ANEPC calls for the “adoption of appropriate behaviour” to prevent consequences of bad weather, namely unblocking water drainage systems, and fixing loose structures”.
