A High Wind Warning will be in effect for the Philadelphia area on Thursday, April 30, until 8 p.m. A powerful storm system will move through the Delaware Valley, bringing heavy rainfall into Friday.
The National Weather Service has issued a High Wind Warning for the Philadelphia area Thursday as the Delaware Valley braces for heavy rainfall.
Forecasters in Mount Holly extended the wind warning to Philadelphia after initially issuing it for coastal portions of southern New Jersey and Delaware.
Based on the latest information we have expanded the High Wind Warning to additional areas of NJ, all of DE, and far southeast PA including Philadelphia. Gusts up to 60 mph are possible especially late morning through late afternoon. Power outages are possible. #NJwx #PAwx #DEwx pic.twitter.com/bjwL1uqMkA
