A powerful storm system will bring significant rainfall and potentially damaging winds to the Lehigh Valley on Thursday.
Rainfall totals of 1 1/2 to 3 inches are anticipated, with wind gusts potentially reaching 30 mph or higher Thursday and 40 mph Friday.
The National Weather Service forecasts periods of moderate to heavy rain developing after midnight Wednesday and continuing through Thursday night.
Rainfall will be widespread, with most areas expecting 1 to 2 inches of precipitation and some localized spots potentially receiving up to 3 inches. An isolated thunderstorm cannot be ruled out, which could further intensify wind conditions.
Wind gusts are expected to be particularly strong, with easterly winds Thursday morning sustained around 20 mph in the Lehigh Valley and potentially reaching 40 to 50 mph — especially in eastern areas.
The weather service says a Wind Advisory may be issued. The strongest winds will likely occur near coastal regions, though the Lehigh Valley could still experience significant gusting.
Friday will bring continued breezy conditions with westerly winds 15-20 mph gusting to 30-40 mph, potentially reaching 50 mph.
