Valley, region under flash flood watch for Wednesday
The Grand Valley and much of southwestern Colorado and southeastern Utah is under a flash flood watch, as heavy rain moving up from the south could fall over the region on Wednesday.
The watch, issued by the National Weather Service in Grand Junction, is effective starting at 10 a.m. Wednesday. Forecasters say “scattered to numerous” thunderstorms with heavy rain are expected over the watch area, developing by late Wednesday morning and continuing into Wednesday night.
The Weather Service says heavy rain could lead to flash flooding in canyons, high water flowing across roads and rock and mud slides. A flash flood watch means conditions may develop that lead to flash flooding.
Grand Junction recently emerged from a 34-day stretch in which no precipitation fell in the city, the sixth-longest streak since the Weather Service began keeping records in 1893.
The forecast officially calls for a 40 percent chance of rain in Grand Junction on Wednesday and a high temperature of 92 degrees. Rain chances continue into Thursday.
