Everything you need to know about the Nor'easter that officials warn could lead to flooding and "widespread power outages."

Rain is expected to begin from Southwest to Northeast in the region from 4 p.m to 6 p.m., according to Hudson Valley Weather. Rain should be heaviest from 11 p.m. Wednesday until 7 a.m. Thursday with the rain tapering off in the southern parts of the area around 6 a.m. Showers could linger in the northern parts of the region until mid-afternoon Thursday.

The Nor'easter is expected to bring two to four inches for rain. Localized flooding is expected in poor drainage areas or areas impacted by clogged storm drains due to falling leaves.

"Localized flooding and power outages, keep in mind that ALOT of leaves will be stripped from the trees so keep a close eye on storm drains. Due to a dry fall, widespread flooding is not expected," Hudson Valley Weather wrote on Facebook. "Storm will be slow mover, winds of this magnitude for 24 hours will likely cause potentially widespread power outages."

Once the rain stops, the area is expected to see high wind gusts. Winds of 20 to 30 miles per hour are expected from 8 a.m. until 8 p.m. Thursday, with wind gusts of 20 to 50 miles per hour from 5 a.m. until midnight Thursday.
