Tropical downpours causing localized flooding in Western New York

More heavy rain is possible in some areas of Western New York through this evening.

BUFFALO, N.Y. — A very warm, tropical weather pattern has set up for the entire Eastern U.S. this week. That pattern has produced a few clusters of heavy, slow-moving thunderstorms around the Western New York area. 

Without an actual cold front to help push the storms along, they're moving at just 15 to 30 mph while producing rainfall rates up to 2.5 inches per hour. Anyone traveling around Niagara, Orleans or northern Erie County this evening should be prepared for quickly-reduced visibility in these storms.

A few of the stronger storms may produce some brief gusty winds as well.

WGRZ received several social media reports and photos of street flooding around the Lockport area between 3:30 p.m. and 4 p.m. Tuesday. According to the National Weather Service, 1.04 inches of rain fell in Lockport. Another observation reports 1.36 inches 1 mile northeast of Lockport. 

This is just one example of what these tropical downpours are capable of. If you encounter a flooded area, do not try to walk, ride or drive through the water.

These scattered thunderstorms will be crawling through the area for the next several hours. Later tonight, rain will fizzle out but the humidity will stick around. More scattered thunderstorms are possible in the Southern Tier Wednesday afternoon, although they are not expected to be as intense as Tuesday's storms.
