NEXT Weather Alert: Widespread rain and wind gusts, flooding possible Sunday into Monday
PHILADELPHIA (CBS) -- A NEXT Weather Alert continues overnight into Monday morning, as a strong coastal storm moves up the coast.
Rain will be heavy and steady overnight, with rainfall rates between 0.50" and 1.0" per hour at times. Because of this, a Flood Watch is in effect all the way through 6 p.m. Monday.
Rain totals could land between 2-4 inches, but isolated pockets of 3-4 inches are possible close to the shore. Expect the heaviest rain to be between 11pm and 3am, with moderate to heavy rain continuing into the early part of the morning commute.
With a warm front attached to this system moving up from the south, temperatures are holding steady overnight in the mid and even upper 50s to near 60 degrees.
There's also a Wind Advisory in effect for all shore points and Delaware Beaches. Wind gusts between 40-50 mph are possible. In the city and the Lehigh Valley, gusts could top 30-40 mph. While outages aren't likely, a few areas could lose power overnight due to gusty winds and heavy rain.
Along the shore, a Coastal Flood Advisory for New Jersey shore points and back bays will be in effect from 10 p.m. Sunday through 4 p.m. Monday. A Coastal Flood Warning for the Delaware Bay goes into effect at 9 p.m. Sunday until 6 a.m. Monday.
By Monday afternoon, we'll clear things up, dry things out and usher in much colder temperatures. It'll go from nearly the 60s to the 40s by the end of the day Monday. A few scattered snow showers and flurries are even possible northwest of Philadelphia as we head into Tuesday.
The good news? After we clear out late Monday, we have a relatively dry and quiet forecast heading into the last full week and weekend before Christmas.
