Tucson, Arizona – An Extreme Heat Warning is in effect for southeast Arizona as temperatures surge toward record levels this week.
According to the National Weather Service in Tucson, afternoon temperatures across the region are expected to range from 95°F to 108°F beginning Thursday, March 19, and continuing through Sunday, March 22.
Forecasters said temperatures are already running above normal and will climb further through the week, creating moderate to major HeatRisk levels during the afternoon hours.
The warning covers much of southern and southeast Arizona, including communities such as Tucson, Nogales, Sierra Vista, Douglas, Safford, and Willcox, where unusually early-season heat could approach or break March temperature records.
Weather Service data shows high probabilities of temperatures reaching 95°F or higher later this week, particularly in Tucson where forecasts show near-certain chances by Thursday and Friday. Some areas may also approach 100°F, which would be extremely unusual for mid-March.
The agency urged residents to begin heat safety preparations now. Officials recommend staying hydrated, limiting outdoor activity during peak afternoon heat, and checking on vulnerable individuals, including elderly neighbors and family members.
Extended exposure to extreme heat early in the season can be especially dangerous because many people have not yet acclimated to high temperatures.
Forecasters said the unusual heat pattern could produce some of the earliest 95°F or 100°F readings recorded for several southern Arizona cities, highlighting the historic nature of the event.
Commuters, outdoor workers, and students traveling during the afternoon hours may experience the most intense heat during the warning period.
The National Weather Service advises residents to monitor updates as the week progresses.
