Philadelphia's weekend forecast calls for rain, north winds gusting near 40 mph and possible tidal flooding. The high is expected to reach about 64°F Saturday, with rain expected. Sunday looks wetter still, with a high near 65°F. Across a period of 48 hours or longer, rainfall could total 1 to 2 inches.

The National Weather Service has a Wind Advisory in effect through 6 a.m. Sunday, September 27, with north winds of 15 to 25 mph and gusts as high as 45 mph. A current National Weather Service forecast also keeps rain chances at 90% Saturday and 100% Sunday. Friday's Hoodline forecast had already reported the wind and coastal flood advisories, along with weekend rain and flood concerns.

Rain And Flooding Build Through Sunday

Saturday's rain could produce between a quarter-inch and half-inch, while Saturday night may add another half-inch to three-quarters of an inch. Temperatures will dip to around 57°F overnight, with strong winds.

Sunday, September 27, is expected to have a high chance of rain. A Coastal Flood Advisory remains in effect through 5 a.m. Sunday for Philadelphia and nearby areas, warning of up to a foot of water in low-lying spots near shorelines and tidal waterways; drivers should never attempt to cross flooded roads.

Brighter Weather Returns After Monday

Monday, September 28, is forecast to be sunny with a high near 85°F. The forecast then turns noticeably calmer: Tuesday should bring a mix of sun and clouds with a high near 76°F, while Wednesday is expected to be sunny and reach about 78°F.

For the wet and windy weekend, residents should secure loose outdoor items, allow extra time for travel and use added caution in high-profile vehicles. The forecast improves quickly next week, but Saturday and Sunday are firmly in umbrella-and-weather-alert territory.
