Big surge of subtropical moisture possible early next week
FRISCO — Hurricane Norbert, now spinning off the coast of Baja, California, could deliver copious amounts of moisture to Colorado early next, according to the National Weather Service, which is already talking about the potential for regional flash flooding.
The Category 3 storm is expected to weaken gradually during the next few days as it moves northwest over cooler water, but the projected path turns the remnant low pressure system eastward, coming ashore over northern Mexico or southern California late in the weekend.
The exact path will determine how much rain falls in Colorado, but National Weather Service forecast maps are showing widespread rain across Colorado, with a bullseye over the north-central mountains.
Grand Junction-based National Weather Service forecasters say subtropical moisture will increase across the Great Basin and western Colorado Monday as a low pressure area off the SoCal coast directs Nortbert’s remnants and more monsoon moisture northeastward.
Storms will be widespread by Monday afternoon with the potential for heavy rain and small hail, as well as a chance for flash floods and debris flows.
