Wild, windy weather across Arizona Friday

Posted: Updated:

PHOENIX -- The National Weather Service in Phoenix has issued a Blowing Dust Advisory will be in effect Friday from 11 am to 8 PM MST and a Wind Advisory remains in effect for the same time period.

Affected areas include La Paz, Yuma, Maricopa, northwest Pinal, and southern Gila counties.

Beginning late Friday morning and continuing into Friday evening expect sustained southerly winds 25 to 35 mph gusting to 50 mph. Areas of lowered visibility between 3 and 5 miles locally below one mile.

Travel may be difficult, especially along east to west oriented roads which includes I-8, I-10, and US60. Strong crosswinds will produce dangerous driving conditions for drivers of high profile vehicles. Widespread areas of blowing dust are likely with localized areas of very dense blowing dust possible. Motorists should be prepared for very quick and drastic reductions in visibility. Small unsecured objects may become airborne.

An Air Quality Alert has also been issued as well as a High pollution advisory for Maricopa County including the greater Phoenix area and Pinal County Friday.

The Arizona department of environmental quality in Phoenix has issued an airborne coarse particle high pollution advisory for the greater Phoenix area for Friday. The Pinal County department of air quality
has issued an airborne coarse particle high pollution advisory for Pinal County including Apache Junction, Casa Grande, Coolidge, and Florence.

An episode of strong and gusty winds is forecast to generate widespread blowing dust that may result in local coarse particle concentrations that pose a health risk. Adverse health effects increase as air quality deteriorates.

A Pacific storm system with strong winds, blowing dust, showers, possible thunderstorms and much cooler weather on the way for Arizona.

Most of the rain is expected to be in south-central Arizona including the greater Phoenix area Friday night. The showers and chance of thunderstorms will probably not reach the Phoenix area until late
Friday evening.

Rainfall amounts are expected to range from less than a tenth of an inch in southeast California and southwest Arizona including Yuma. Rainfall amounts are expected to range from 1 tenth
of an inch to more than a quarter of an inch in the south-central Arizona desert including the Phoenix area to more than a half inch in the higher terrain north and east of the greater Phoenix area.

Colder air will move in behind the front with early morning temperatures dropping into the upper 30s and 40s in most desert locations Saturday morning. Temperatures are expected to be 10 to 20 degrees colder Saturday with highs between 60 and 70 in the desert areas including the Phoenix metro area.

The snow level will lower to near 5000 feet by Saturday morning. However, most of the precipitation will have ended by then, so no significant snowfall accumulation is expected at that level.
