Central Pennsylvania is bracing for flash flooding as repeated rounds of heavy rain overnight could cause rapid flooding in vulnerable areas. The National Weather Service in State College has issued a Flood Watch for 13 counties, including Columbia, Lycoming, Union, and Northumberland, with the greatest risk of flooding in low-lying and flood-prone areas through 8 a.m. Tuesday.
Flood Watch Issued for 13 Counties
The Flood Watch remains in effect through Tuesday morning, with thunderstorms expected to produce heavy rainfall at rates of 1 to 2 inches per hour. Localized rainfall totals could exceed 3 inches in some areas, leading to a higher risk of flash flooding. Creeks, streams, and roads near steep terrain or poor drainage systems are particularly vulnerable.
Communities along the West Branch Susquehanna River, such as Williamsport, Lock Haven, and Sunbury, should be on high alert for rapidly rising water levels. Flash flooding is also likely to affect major routes like PA-405 and US-15 during the morning commute, creating potential disruptions for drivers.
Safety Tips for Residents
Residents are urged to take the following precautions to stay safe:
- Avoid driving on flooded roads, as conditions could worsen quickly.
- Keep your cell phone charged and have backup power available in case of outages.
- Stay updated with local alerts and Flash Flood Warnings, which may be issued if conditions worsen overnight.
- Expect potential delays in schools and businesses, especially if rainfall totals are significant and road conditions become hazardous.
Cause of the Flooding Risk
The heavy rain is expected to fall in multiple rounds, with thunderstorms contributing to rapid rainfall accumulation. Areas with poor drainage systems or those near creeks and rivers are at a heightened risk of flash flooding. Communities along the West Branch Susquehanna River will be particularly susceptible to rising water levels.
What to Expect After 8 a.m. Tuesday
While the Flood Watch is set to expire at 8 a.m. Tuesday, residents should remain alert as storms could persist or intensify, prompting additional alerts. Flash flooding may continue to impact travel and flooding-prone areas until conditions improve. Be prepared for possible disruptions and monitor weather updates closely.
