PHILADELPHIA (CBS) — The first named tropical storm of the Atlantic hurricane season is bringing soaking rain to the Delaware Valley to finish the work week as it joins up with a separate storm moving through the Northeast.

Tropical Storm Andrea made landfall along Florida’s Big Bend on Thursday around 5:45 p.m. and has gathered forward speed. As it continues to travel quickly up the East Coast, heavy rain and flooding concerns will likely be the legacy the storm leaves behind.

Flood Concerns

The heaviest rain will fall Friday afternoon and evening, with a general swath of 1-3”. Some locations – especially west of Philadelphia – could end up with 4″ of total rainfall.

Flash Flood Watches are in effect through most of the tri-state area through late Friday night. In addition, Flood Advisories have been issued in locations that saw a lot of rain Friday morning, mainly from New Castle County, DE up the I-95 corridor to central NJ and points north and west from Chester County up to Upper Bucks.

Wind Impacts

While the Delaware Valley will definitely experience wind as the storm rolls through, we shouldn’t see too much in the way of wind damage or storm surge. This is mainly because the strongest wind stays offshore and the storm is such a fast-mover.

However, we’ll still have gusts as high as 30-40 mph inland, as high as 45-50 mph along the shoreline.

Minor coastal flooding may still occur along the NJ/DE beaches, especially at high tide through Saturday.

When Does It End?

Thankfully, the weekend shows vast improvement as Andrea’s remnant moisture pulls away Saturday morning. We’ll still see a few residual steady showers, especially Saturday. But in general we have a chance to dry out, see a bit more sun, and get temperatures back to the low 80s.
