Intense But Short Storms Swamp Streets

Fast-moving and intense thunderstorms moved along the Main Line Monday, swamping some streets in Tredyffrin and Easttown and causing trees to come down further east in Lower Merion and parts of southern New Jersey.

Driving along Lancaster Avenue as the skies opened up showed exactly how fast intense summer storms can overwhelm drains. The rain started moving into the Devon area shortly before 5 p.m. and skies were clearing by 6:30 p.m.

The National Weather Service issued an advisory Monday warning about the possibility of flash flooding. Drivers in the right lanes of Lancaster Avenue in parts of Wayne and Devon were left to navigate swamped roads as waters gushed into any low lying shoulders.

The storms swept out high humidity, leading to a much more pleasant evening Monday. The weather service forecast calls for a high in the low 90s but with lower humidity Tuesday. Rain is expected to move in again on Wednesday with a high of only 77.
