The Portuguese Institute of the Sea and Atmosphere (Instituto Português do Mar e da Atmosfera or IPMA) warns of a sharp temperature drop in the Azores this Tuesday and Wednesday. A polar air mass could bring snow to areas above 800 meters in the Central and Oriental island groups. Those in the archipelago should be aware that minimum temperatures are expected to fall between 7 and 9 degrees Celsius.

Context & Explainers
IPMA (Instituto Português do Mar e da Atmosfera) is Portugal's national authority for weather, ocean, and climate monitoring. It produces weather forecasts, issues severe weather warnings, monitors seismic activity, and provides marine and atmospheric data.
IPMA uses a four-level color-coded warning system: green (no risk), yellow (potential risk), orange (moderate-to-high risk), and red (extreme risk). These warnings cover conditions such as heavy rain, strong winds, extreme heat, cold snaps, rough seas, and snow.
Residents should monitor IPMA forecasts during storm season (typically October–March) and heatwaves (July–August). IPMA bulletins are used by civil protection authorities, transport operators, and local councils to make decisions about road closures, school suspensions, and evacuation orders.
