Strong and gusty winds—up to 50 mph—are the biggest hazard from a day of rain and thunderstorms.
"Highest threat potential is from this afternoon through this evening. This potential will be enhanced in areas of heavy showers or thunderstorms," the National Weather Service states in today's weather alert for the lower Hudson valley.
The possible impact: downed power lines, downed trees—and power outages, the NWS says.
Winds this strong can also make driving difficult, particularly for vehicles with high profiles (such as SUVs and trucks), the NWS warns.
The NYS Thruway warns vehicles to use reduced speed on the Tappan Zee Bridge (35 mph) where high winds are ripping down the Hudson.
In Tarrytown and Sleepy Hollow, the NWS forecast calls for heavy rain, totaling up to two inches, before the storm front moves out Wednesday night.
