In response to snowmelt and 1-2″ of rain, rivers will rise quickly and start to flood Friday night and Saturday. The heaviest axis of rain will be over New York & northwest Vermont. Minor to moderate flooding is likely. This type of flooding can inundate low lying areas and it can even washout & close roads. Be prepared for detours, lane closures and perhaps evacuations if you live immediately along a river. The more south you are, the flood threat is less but you’ll still need to be vigilant around the Otter Creek and other rivers near the Upper Valley.
Rivers in northern New York will crest Saturday afternoon and fall below flood stage Sunday morning. Rivers in north central & western Vermont will crest between Saturday morning & Saturday afternoon then fall below flood stage by Sunday afternoon. Rivers in eastern Vermont & New Hampshire will crest Saturday night and slowly fall below flood stage by Monday morning.
Meanwhile, Lake Champlain will rise but it will take longer than the rivers. It’s expected to reach minor flood stage Sunday afternoon. Water will flow into low lying areas along the lake and start to cover piers and docks.
Steady rain will keep moving east of us Saturday and Sunday. This is good news for Easter Sunday plans! We’re expecting a mix of sun and clouds with just a small chance at isolated showers; highs will make it well into the 60s. Next week will be slightly unsettled with a daily shot at showers but no big washouts. Highs Monday to Friday will be on either side of 60° with lows in the 30s & 40s.
Stay safe, have a great weekend and happy Easter!
