Meteorological Warnings User’s Guide

It is responsibility of IPMA to ensure weather watch and to issue warnings whenever adverse meteorological events are predicted or observed.
The purpose of this page is to warn the Civil Protection Authorities and the general public of the occurrence of hazardous weather conditions that may cause damage within 24 hours.
Warnings are issued at district level for different meteorological parameters. A range of colours reflects the intensity of the phenomenon.

The colours mean:

Warnings are issued in case of: strong wind, heavy rainfall, snowfall, thunderstorm, cold, heat, persistent fog and sea disturbance.

Taking into account the different characteristics of weather events, their incidence and effects, Issuance Criteria (see criteria) have been established.

If a warning is issued for two or more different parameters, for instance wind and rainfall, with different warning levels, the district will appear in the colour and with the icon corresponding to the higher risk. Information on the second parameter will be shown on clicking on the district.

For further information on the warning, view the districts and islands listed on the left of the map.

When warnings are issued, please be informed of the advices and self-protection actions divulged by: National Service of Fire Combat and Civil Protection - AENPC (Civil Protection ) by:  Directorate General for Health - D.G.S. (Direção-Geral da Saúde).
