Season's First Heat Wave Strikes On Memorial Day

According to the National Weather Service in Mount Holly, the first heat wave of the season is likely to occur today through Wednesday across the Delaware Valley.

Temperatures will rise into the lower to mid 90s today, tomorrow and Wednesday in areas from Trenton through Philadelphia and Wilmington including Bucks and Montgomery counties.

The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible.

This could be life threatening for those without air conditioning or who work outside during the hottest time of the day. Children, the elderly and pets are at the greatest risk.

The Weather Service says to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors.

The heat advisory remains in effect from noon today to 9 p.m. this evening. The excessive heat watch remains in effect from Tuesday afternoon through Wednesday evening.
