|High wind levels have the potential to suspend particulate matter into the air. High levels of PM10 may pose an impact to public health. It is recommended that active children and adults, and people with respiratory disease, such as asthma, limit their outdoor activities.
Potential increases in PM10 concentrations may increase to moderate or unhealthy level.
|Imperial County Weather Synopsis|
|SYNOPSIS FROM THE SAN DIEGO OFFICE
High pressure aloft and weak offshore flow will continue hot and very dry weather west of the mountains through Tuesday with high temperatures in the valleys and inland coastal areas in the 90s to around 100. Cooling and moisture will begin to spread inland with onshore flow Tuesday night and Wednesday, with greater cooling on Thursday and Friday as a trough of low pressure moves inland along the West Coast. This will bring more cloud cover and gusty west winds in the mountains and deserts. Dry and hot again next weekend due to strengthening high pressure aloft and offshore flow.
SYNOPSIS FROM THE PHOENIX OFFICE
High pressure will persist across the region through the middle of the week allowing for continued very warm and dry conditions. High temperatures for lower desert communities will generally reach into the middle and upper 90s. Somewhat cooler weather with more cloud cover will arrive during the end of the week. High pressure returns quickly by the end of the weekend, sending temperatures back to above normal readings.
