BUFFALO, N.Y. (WKBW) — Power outages are possible on Monday! High wind warnings and lakeshore flood warnings posted!

High Wind WARNING in effect for Northern Erie, Niagara, Orleans, Genesee, and Wyoming Counties from 10am Monday through 2am Tuesday. Winds will gust out of the southwest near 60 miles per hour.

High Wind WARNING in effect for Southern Erie and Chautauqua Counties from 5am Monday through 11pm Monday. Winds gusting out of the southeast at 60 miles per hour.

High Wind WARNING for Cattaraugus and Allegany Counties 11am Monday to 11pm Monday. Winds will gust near 55 miles per hour.

Lakeshore Flood WARNING for Erie, Niagara, and Chautauqua Counties from 12pm Monday to 8am Tuesday

Confidence remains HIGH for a strong and damaging wind event especially northeast of Lake Erie on Monday.

An area of low pressure will swing a cold front through the area early Monday afternoon. This front will help create surface winds that could peak near 60 miles per hour. We can also expect a line of thunderstorms to develop. If skies clear out quickly Monday afternoon we would have an even greater chance of experiencing wind gusts of 65mph.

The ground will be saturated from a soaking rain early Monday. That means shallow-root trees like pine trees will more easily come down. Power outages, tree damage, and property damage will be likely on Monday. Models have been consistently forecasting strong damaging winds Monday through Monday evening.

From the Buffalo National Weather Service: "Lake Erie...Indications are that this will be a HIGH END seiche event. Very strong southwest winds of at least 35 kts for a longer duration will cause lake shore flooding along the Lake Erie shoreline and the Upper Niagara River. Water levels will reach at least 10 ft at Buffalo (flooding begins at 8 ft). Even levels of 11 ft are possible, which is higher than what was reached during the Halloween seiche event in 2019. Levels this high not only impact the typically vulnerable locations, but also flood portions of the Buffalo Harbor and Canalside, as well as the Upper Niagara River including portions of Grand Island and Cayuga Island. Levels will rise rapidly and reach the highest levels Monday afternoon or early evening. Lakeshore Flood Warnings continue for Chautauqua, Erie, and Niagara counties."
