Flash flood watch extended for GJ, region
Rain has already dampened parts of the Grand Valley this morning, as forecasters predicting heavy rainfall and possible flooding for the region have extended a flash flood watch.
The watch, which blankets all of western Colorado and eastern Utah, is now in effect until midnight Friday morning, according to the National Weather Service in Grand Junction. It previously was set to expire at 6 p.m. Thursday.
Forecasters say deep, subtropical moisture combined with disturbances in the atmosphere will trigger scattered to numerous showers and thunderstorms this afternoon and evening, with some storms continuing overnight. Storms will again increase on Thursday, creating continued flash flooding risks due to already saturated ground. Some storms will produce heavy rainfall in a short period of time, with rainfall of an inch or more possible.
Residents should be aware that flash flooding, rockslides and debris flows could occur near steep terrain and normally dry creeks.
Officially, the forecast for Grand Junction calls for a 70 percent chance of rain today and tonight and a high of 81 degrees today. Thursday’s forecast calls for a 50 percent chance of rain and a high of 83 before drier air moves in Friday.
