|February 16 2018|
|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|
Generally, partly sunny skies are forecasted through the weekend with temperatures into the mid to high 70s. There will be increasing breeziness late Saturday and into Sunday for some parts of Imperial county, particularly the southwest corner where gusts could reach 30 mph in the afternoon. President's Day on Monday should be sunny but a bit cooler.
DISCUSSION FROM THE SAN DIEGO OFFICE
Dry and warmer through Saturday with gusty Santa Ana winds near the coastal foothills and below passes and canyons into this morning. For Sunday and Monday a cold low pressure system moving southward through the western states will bring stronger onshore flow with cooling gusty west winds in the mountains and deserts and chances for mostly light precipitation along and west of the mountains for late Sunday into Monday evening. Drier and continued cool for Tuesday through Thursday.
DISCUSSION FROM THE PHOENIX OFFICE
A weather system will be exiting the region with showers decreasing today. Any remaining rainfall will affect higher terrain areas to the east of Phoenix. Warmer and drier weather will spread into the region this weekend, but another weather system will descend into the area the first half of next week. This system will likely bring cooler temperatures along with at least a few showers to portions of south central Arizona.
