Flood Watch

CanisLupusArctos · 04-06-2009, 11:01 AM

This thread is for the monitoring of the spring flood situations, 2009.

The National Weather Service has issued a flood watch for the entire state of NH except extreme southwest (Keene area) and the entire state of Maine for the storm that is moving into the area this afternoon. The lake level has been rising all week.

A great deal of rain is now moving up from the south. This is the eastern (warm) side of the winter storm that is bringing heavy snow from the Great Plains eastward to Chicago, where baseball's opening day has been snowed out. The storm is drawing unseasonably cold air out of Canada and wrapping it around to the south where the cold front is touching off severe weather -- tornado watch in effect as far north as Virginia.

On the east side of the storm (ours) the low pressure center is pulling moisture and warmth up from the south, into the path of the cold air wrapping around from the north. This interaction is milking the moisture out of the air in the form of heavy rain and thunderstorms, which will be our weather later today and tonight.

The heavy rain combined with mountain snowmelt may make rivers go over their banks. If that happens, you will hear of a flood warning for the rivers affected, broadcast on radio or TV.

The rivers and the lake will continue to rise after the rain has stopped, as runoff finds its way in.
