Thunderstorms possible across St. Lawrence County; high wind warning and flood watch issued
Wednesday, January 30, 2013 - 9:18 am

 

The National Weather Service has issued a high wind warning and a flood watch as temperatures continue to rise bringing a chance for thunderstorms across the North Country.

A high of 56 is expected today, but temperatures will drop rapidly Thursday to as low as 3 degrees.

The warning is in effect until from 4 a.m. to 7 p.m. Thursday.

Sustained winds of 20 to 30 mph are expected throughout the day Thursday and gusts could reach as high as 65 mph, according to the National Weather Service.

The combination of rainfall and snowmelt on top of frozen ground will cause river rises and ice breakup. Ice jams can occur where ice moving down a river is held up at constrictions such as bridges, islands, or bends in the river. Water can quickly back up behind the jam and cause flooding with little or no advance warning.

Runoff from rainfall and snowmelt may also cause localized flooding of poor drainage areas.
