Tucson, AZ – Powerful easterly winds could sweep across southern Arizona beginning late Thursday, bringing gusts as high as 70 mph, blowing dust and potentially dangerous travel conditions through Friday night. The National Weather Service has issued a High Wind Warning for Tucson and surrounding communities from 11 p.m. Thursday until 11 p.m. Friday, Oct. 16, followed by a Wind Advisory extending into Saturday afternoon. Forecasters warn that damaging winds could topple trees, affect power lines and produce widespread outages, particularly in areas exposed to stronger mountain driven gusts.
According to the National Weather Service in Tucson, east winds of 35 to 45 mph are expected during the High Wind Warning, with gusts potentially reaching 55 to 70 mph. The warning covers a broad portion of southern and southeastern Arizona, including central Pima County, the Tucson metropolitan area, Santa Cruz County and portions of Cochise, Graham and Greenlee counties. Northern Graham and Greenlee counties are excluded from the specified warning area.
Damaging Winds and Blowing Dust Threaten Southern Arizona The strongest winds are expected along the leeward, or western, sides of mountain ranges, where terrain can accelerate airflow through gaps and east west oriented valleys. Communities including Tucson, Marana, Vail, Benson, Sierra Vista, Nogales and Willcox are among the locations identified in the National Weather Service warning.
The combination of strong sustained winds and potentially damaging gusts could create hazardous conditions across exposed roads and desert areas. Forecasters warn that blowing dust may briefly reduce visibility below one mile, creating additional concerns for motorists traveling through open terrain.
Interstate 10 between Tucson and Willcox, Interstate 19 toward Nogales and other exposed southern Arizona highways could experience difficult driving conditions. High profile vehicles, including tractor trailers, recreational vehicles and vehicles towing trailers, may be especially vulnerable to strong crosswinds. Although no specific highway closures are identified in the supplied warning, drivers should be prepared for rapidly changing visibility and wind conditions.
The National Weather Service also warns that trees and power lines could be brought down by damaging gusts, potentially resulting in widespread electrical outages. Residents should secure patio furniture, trash containers and other lightweight outdoor belongings before conditions deteriorate Thursday night.
High Wind Warning Continues Through Friday Night Thursday will initially bring sunshine and temperatures near 85 degrees in Tucson, with relatively light winds becoming northeasterly during the afternoon. Conditions are expected to change after midnight, when easterly winds strengthen and patchy blowing dust begins developing.
The local forecast calls for east winds increasing to 18 to 28 mph after midnight, with gusts reaching 40 mph. Temperatures will remain relatively mild, falling to approximately 67 degrees by early Friday.
Friday will bring the most significant weather concerns as the High Wind Warning continues throughout the day. The Tucson point forecast indicates sustained east winds of 25 to 31 mph, with gusts reaching 45 mph, while the broader warning area could experience gusts as high as 70 mph.
Blowing dust may persist during the afternoon, particularly across exposed desert locations. Temperatures are expected to reach approximately 80 degrees, but the strong winds could complicate outdoor activities, construction work and travel.
Wind Advisory Extends Into Saturday Although the High Wind Warning is scheduled to expire at 11 p.m. Friday, windy conditions are expected to continue into Saturday. A Wind Advisory takes effect immediately afterward and remains in place until 2 p.m. Saturday, Oct. 17.
During the advisory period, east winds of 25 to 35 mph are expected, with gusts reaching 50 to 60 mph across the affected region. Tucson's local forecast calls for gusts reaching approximately 46 mph Friday night before conditions gradually improve Saturday.
Saturday will remain breezy, with mostly cloudy skies and a high near 76 degrees. By Sunday, sunshine returns and temperatures climb toward 83 degrees as the strongest winds subside.
The National Weather Service advises residents to secure loose outdoor objects and exercise particular caution when traveling in high profile vehicles. Anyone planning to drive through exposed desert corridors late Thursday through Saturday afternoon should monitor updated weather alerts and road conditions.
