A blast of heavy rain, gusty winds and thunderstorms will sweep northward along the Atlantic Seaboard on Tuesday.
Enough rain, wind and urban flooding can occur to lead to significant airline and highway delays.
The combination of melting snow and ice from Monday and heavy rain on Tuesday can be enough to cause urban flooding. Excess water on the roads will raise the risk of hydroplaning, while the nature of the rain and wind will create low visibility for motorists.
The bulk of the rain and wind will hit Atlanta and Charlotte, North Carolina, and Columbia, South Carolina, during early Tuesday morning. Motorists traveling along Interstate 85, I-77 or I-20 should be prepared for sudden low visibility.
The heavy rain and poor visibility will spread northward along the I-95 corridor as Tuesday progresses.
The worst conditions will affect Washington, D.C., Baltimore, Philadelphia and Norfolk, Virginia, during the midday hours on Tuesday. New York City targeted by the heavy rain and wind during Tuesday afternoon. Boston can expect increasing winds on Tuesday afternoon with the heaviest rain toward evening.
The heavy rain could be accompanied by thunder and lightning and locally strong wind gusts.
Wind gusts, generally between 40 and 50 mph, could become strong enough to break off some tree limbs and cause sporadic power outages.
Strong southerly winds will also push ocean, bay and sound waters northward. As a result, there can be coastal flooding, especially at times of high tide on Tuesday.
Rain and wind will diminish from southwest to northeast later Tuesday and Tuesday night.
The balance of the week will feature benign weather conditions with fewer disruptions to travel.
On Wednesday, a much weaker storm, relative to the system from Monday into Tuesday, will affect parts of the central and southern Appalachians to the mid-Atlantic coast with a bit of wet snow and rain showers.
