Tropical Storm Isaias is forecasted to arrive in the Philadelphia region on Monday night and is expected to bring heavy rain, flooding, and strong winds through Tuesday night, according to the National Weather Service.

Significant rainfall across the entire region is expected to start Monday night and continue through Tuesday night, potentially leading to flash flooding and poor drainage flooding for inland locations such as along the I-95 corridor.

Stream and river flooding is also possible, especially in Southeastern Pennsylvania and parts of New Jersey. 

Strong winds are expected to arrive during the day on Tuesday, with wind speeds potentially reaching 73 MPH. The strong winds could lead to tree and power line damage.

The highest risk of wind damage is expected along the Jersey Shore, leading to an increased risk of rip currents and swells starting this weekend and continuing through at least Wednesday.

Tropical storms conditions are possible, especially for coastal locations along the Jersey Shore. Heavy rain could lead to coastal flooding and storm surge, especially around high tide on Tuesday.

There is still some uncertainty over the future track, intensity, and timing of the storm, the National Weather Service said. Any change in the path of the storm will impact how far inland tropical storm force winds extend.
