The National Weather Service issuing a flash flood Warning for Monroe County through the morning, and one of the areas hit hardest by the rain that started overnight is Henrietta.

Storm drains on Calkins Road were not able to handle the amount of rain falling. Firefighters said that water got so deep, they had to close the road for a time.  

Henrietta fire crews were busy answering several calls for high water and stalled cars.

"If you see that the road is flooded don't drive through it,” said Henrietta Assistant Fire Chief Mark Cholach. “The reason is, you don't know where the road stops and the side of the road or a ditch or a pond or whatever could be there. So, if somebody ends up going off the road, their best bet is to stay in their car and wait for help."

He confirmed his crew responded to about 25 jobs in just two hours’ time.

Overnight, rain caused water to pool on many major roads. Calkins Road was closed for a short period due to localized flooding but later reopened.

In Brighton, flooding on the I-490, just before exit 441, caused trouble for drivers on both sides around midnight.

Multiple cars were off the road with at least one into the barrier.

Police had to close lanes while the Brighton Fire Department worked to clear out drains to remove water from that area.

It's not clear if anyone in those cars were injured.

The National Weather Service is providing a word of caution to those who might try driving through pooled water. It said people underestimate the power of water and it is never safe to drive or walk into flood waters.

Just six inches of fast moving water can knock over an adult; in 12 inches of rushing water, a small car can be carried away.
