Buffalo, N.Y. (WBEN) - If you have outdoor plans Saturday, you'll need a tent or umbrella as waves of steady, and sometimes heavy, rainfall continue across the region.

Overnight rainfall across the Buffalo metro area and northern portion of Western New York has been significant enough to cause concerns about flooding across the region.

In addition to a flood watch for the entire region through late Saturday, a flood warning is posted for much of the area through Saturday afternoon as more steady and heavy rain is forecast to continue.

CHECK: WBEN First Alert Forecast plus flood advisories

The rain is expected to lighten and become more spotty late in the day before subsiding for a much better Sunday across Buffalo-Niagara.

The National Weather Service in Buffalo has issued a * Flood Warning for Urban area and small stream in... Northeastern Erie County in western New York... Genesee County in western New York... Northwestern Livingston County in western New York... Northwestern Monroe County in western New York... Niagara County in western New York... Orleans County in western New York...
