Flash flood watch for all of WNY; rainy overnight and Tuesday

Forecasts call for showers and thunderstorms to drop an additional half-inch of rain or more across portions of Western New York through early Tuesday afternoon as another moisture-laden weather system crosses the area.

That led the National Weather Service Monday to issue a flash flood watch for all counties in Western and Central New York.

"Recent significant rainfall has resulted in many areas with saturated ground and streams running high," the weather service statement said. "Any thunderstorm overnight into early Tuesday will have to potential to produce very heavy rainfall in a short period of time. This may lead to flash flooding."

Nearly 1.4 inches of rain had fallen at the Buffalo Niagara International Airport between Friday and Sunday alone, according to weather service data.

National Weather Service shows flash flood watches in effect across western and central New York State through Tuesday.

Areas most prone to flash flooding could be in the Finger Lakes, Genesee Valley and across the Southern Tier, the watch stated.

Forecasters warned those around rivers and creeks to "monitor weather conditions closely" and advised them to "move to higher ground if flooding is observed or a warning is issued."

Motorists are also cautioned to heed weather conditions and not attempt to drive through running flood waters. The Binghamton office of the weather service posted a video taken over the weekend from the Watkins Glen area showing the dangers of failing to heed such warnings.

Heavier rainfall was expected further south, forecasts show.

Here are some of the forecast rainfall totals around Western New York through about 2 p.m. Tuesday, according to the weather service: Jamestown, 0.56 inches; Fredonia 0.51; Angola, 0.47; Orchard Park and Buffalo, 0.43; Clarence Center, 0.41; Lockport, 0.38 and Wilson, 0.33. Amounts could be higher in heavier thunderstorms.

Clearing was expected to occur by Tuesday night with sunshine returning Wednesday and temperatures in the low 70s, the forecast shows.
