The combination of heavy rains and southeast winds overnight could bedevil some motorists this afternoon.
The National Weather Service has hoisted a coastal flood warning for all the areas along the Delaware River from Bucks to New Castle Counties.
High tide at Philadelphia is at 3:35 p.m., and roadway flooding along the likes of Delaware Avenue and the Admiral Wilson Boulevard is likely.
The weather service attributes the threat to runoff working its way north to south along the Delaware, and the after-effects of strong winds from the southeast.
Those winds have swung around, and tomorrow could even bring the opposite phenomenon -- a blow-out tide.
But the short-term issue is flooding.
It certainly isn't snow. In its morning briefing, the Commodity Weather Group in Washington notes that the U.S. models now see warmth lingering into the first week of February.
