Potential increases in PM10 concentrations may increase to moderate or unhealthy level.

Imperial County Weather Synopsis
A strong, but mostly dry, cold front will continue to move through the area today from the northwest. Gusty north to northwest winds will develop region wide behind the front, the strongest across Southeast California and down the Colorado River Valley. Strong wind gusts along with periods of significantly reduced visibilities in blowing dust/sand and overall degradation of regional air quality are the main weather hazards today. Gusts 40 to 50 mph can be expected near the Colorado River cities of Parker, Blythe, Yuma and over/near Joshua Tree National Park. Northwest gusts to 30 mph will develop in south central Arizona near the cities of Wickenburg, Phoenix, Gila Bend, Coolidge and Casa Grande. Limited moisture will be associated with the cold front, so only a slight chance of showers can be expected in Gila County, mainly for locations closer to the Mogollon Rim and White Mountains. Winds will begin to diminish into the evening, but still remain breezy to locally gusty down the Colorado River Valley

Strong gusty Northwest winds will slowly diminish to breezy conditions early tonight with the exception of steady 15 to 25mph north winds down the Colorado River overnight on Saturday strong 30 to 40mph North winds are forecast to redevelop along the Colorado River breezy elsewhere. No rain

A trough digging south through Nevada and Arizona Strong creating gusty winds today…which will eventually spreading into portions of the Inland Empire and portions of inland Orange County on Saturday

A low pressure system moving from the Great Basin to the Southern Rockies will bring period of gusty Northwest to North winds today and North to Northeast winds tonight into Saturday. High temperatures for coastal and valley areas will warm into early next week and into the middle of next week for the mountains and deserts. Weak onshore flow will return near the coast on Tuesday and strengthen for the latter part of the week as a low pressure system approaches California. Slow cooling will develop near the coast on Tuesday then spread slowly inland through the end of the week
