Overview
- The National Weather Service in State College issued multiple severe thunderstorm warnings for south‑central Pennsylvania on Tuesday after radar and reports showed 60 mph wind gusts, rotation and small hail.
- Doppler radar indicated 1 to 1.5 inches of rain had already fallen with up to 1.5 more possible, and a Flash Flood Warning remains in effect for parts of Lancaster and Lebanon counties because flash flooding is ongoing or expected shortly.
- Warnings and impact statements say the storms can damage roofs, siding and trees and that heavy rain may flood small creeks, underpasses and low‑lying urban areas, creating hazardous driving conditions.
- Officials and local media urged people to take cover in a sturdy building, avoid driving through flooded roadways and report observed flooding to emergency services for rapid situational awareness.
- Meteorologists tracked the storms as lines moving east or southeast at about 20–35 mph using radar and law‑enforcement reports, which raises the risk of quick changes in storm intensity and short‑notice hazards on interstates such as I‑81, I‑83 and the Pennsylvania Turnpike.
