Heavy Rains May Cause Flash Flooding In Northern New York

     Although Champlain Valley Weather does not regularly cover any other then the Champlain Valley of New York, I have decided to do a special post, on a potentialy hazardous situation in St. Lawerence County New York, that's ongoing right now.

     As of 6:10PM National Weather Service Doppler radar indicated a strong thunderstorm with torrential rain, nearly stationary over parts of North-Central St. Lawrence County in Northern New York. National Weather Service Doppler radar indicated that rainfall rates have reached nearly 3 inches per hour just northeast of Potsdam, and just east of Norwood. Doppler radar estimates that 2.5 to 4.0 Inches of rain has fallen. This storm is slowly drifting to the northeast, but moderate to heavy rain continues to persist over the same areas. The National Weather Service has issued a Flood Advisory for this area, but a Flash Flood Warning may be needed if rain persists much longer. Of additional concern is additional thunderstorms developing in the same general area, along with a very slow moving swatch of moderate to heavy rain approaching from the west. This large area of rain will likely begin to effect this area within the next couple of hours. Additional rainfall totals of 1-2 inches with locally up to 3 inches can be expected by later tonight. This area will be watched very closely for the potential of Flash Flooding. If you live along Plum Brook or Tucker Brook or their tributaries it is strongly recommended to keep a very close eye on the level of the water. If you notice very rapidly rising water it is strongly recommended to move to higher ground.

     Also to note, heavy rain, and thunderstorms are developing and remaining nearly stationary in other portions of St. Lawrence County, and nearby Franklin County. Other locations that will need to be monitored for potential flooding problems are Slab City, Madrid, Madrid Springs, Waddington, and other towns near Route 345 from Potsdam, to Waddington. Also areas near Gile, and Spring Cove, and areas just west of those towns in the Adirondack Park Preserve.

   Stay tuned for any further updates!
