Thunderstorms shifting over the Northeast will take aim at the I-95 corridor on Tuesday, possibly impacting major cities during the evening commute.
Showers and thunderstorms are forecast to expand across the region throughout the day on Tuesday with the heaviest storms developing during the afternoon.
New York City, Philadelphia, Baltimore, Washington, D.C., and Montreal, Quebec, are just a few cities that could feel the impacts from these storms.
Some of the stronger storms may also produce brief wind gusts up to 45 mph.
Localized flash flooding will be the biggest concern as moisture originating from the Gulf of Mexico fuels downpours that can drop over an inch rain as the storms roll through.
These heavy downpours may lead to travel delays along the I-95 corridor during the evening commute, especially those on the roadways.
Slower traffic and reduced visibility should be expected for anyone driving through these downpours, as well as the risk for hydroplaning.
Delays at the airports are also possible due to the poor take-off conditions that thunderstorms produce.
