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

Imperial County Weather Synopsis
A strong high pressure system is forecast to build and expand over the region to levels not seen in a while. As a result, record high temperatures are forecast well into the danger zone, ranging from 115 to 120 degrees on the lower deserts Sun-Wed. An Excessive Heat Warning is posted Sun-Wed making it a prolonged heat wave

The large Pacific low pressure system along the west coast that had kept afternoon temperatures below normal for the past six days will weaken today. As a result, a high pressure system will slowly build over the region through Friday, then intensify Saturday through next week. Record high temperatures and dangerous high heat Sunday through Wednesday has prompted the issuance of an excessive Heat Warning

A strong and large area of high pressure will create very hot weather inland this weekend through early next week. High temperatures up to 20 degrees above normal are expected by Sunday, with areas of the Coachella Valley and low desert approaching 120 degrees. Avoid outdoor activities during the hottest part of the day if possible. Strenuous outdoor activity in heat of this magnitude could be deadly

Fair and seasonal weather, but with less extensive coastal clouds, will continue through Friday. A high pressure ridge will strengthen this weekend and bring very hot weather through at least early next week. High temperatures will be well above normal, possibly breaking several records, with Monday being the hottest day. A slow cooling trend is expected by the middle of next week as the upper ridge weakens
