Severe Weather Information Centre, enhancing the availability of authoritative warnings and information related to extreme and/or potentially high-impact weather, water, and climate events from WMO Members, is one of the core components of WMO GMAS Framework in support of the Early Warnings for All Initiative.

The Met Office has issued severe weather warnings for heavy rain in central and south-western Scotland all day Friday, and in parts of Yorkshire for Friday morning. The more extreme warnings remain near the English-Welsh border, around the rivers Severn, Wye, and Lugg, where many people have already experienced flooding.

An Extreme Wind Warning is issued when winds over 115 mph (100 knots, or Category 3 or greater on the Saffir-Simpson Hurricane Wind Scale) threaten an area for one to two hours. These warnings are almost exclusively issued during landfalling major hurricanes on the United States.

The issuance of an Emergency Warning for an area indicates a level of exceptional risk of a magnitude observed only once every few decades. Residents should pay attention to their surroundings and relevant information such as municipal evacuation advisories and evacuations, and should take all steps necessary to protect life.
