|March 2 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|
Temperatures will hover in the mid 60s to low 70s during the weekend. On Saturday, particularly during Saturday afternoon, it will be breezy across much of Imperial County with winds reaching up to 25 mph in some areas. The southwest portion of the county could see gusts reach 35 mph. Patchy blowing sand and dust is likely.
DISCUSSION FROM THE SAN DIEGO OFFICE
A low pressure system along the West Coast will move slowly southward today through Saturday then move inland Saturday night and Sunday. Precipitation will spread slowly southward across far southern California through this evening with scattered showers following through Saturday decreasing from the northwest Saturday night. High pressure aloft near the West Coast and surface high pressure over the Great Basin will bring a warming trend for Monday through Wednesday with periods of gusty northeast winds near the coastal mountain slopes and below passes and canyons. Weak onshore flow will return the latter part of next week with cooling spreading inland.
DISCUSSION FROM THE PHOENIX OFFICE
A warming trend will continue today ahead of an approaching low pressure system. High temperatures will likely reach the mid 70s across the lower deserts, making it the warmest day in nearly two weeks. A frontal boundary extending from the aforementioned low pressure system will move through the region Saturday, though it will be moisture starved. In terms of sensible weather, biggest impact will be an increase in wind ahead of the front, particularly across southeastern California where gusts could reach 30 mph. High pressure building across the region will then result in a warming trend through next week, with temperatures reaching the 80s as early as Wednesday across the lower deserts.
