Tucson drivers and residents should prepare for a wet Wednesday as thunderstorms are expected with a 60% chance of showers and storms after 11 a.m. Heavy rainfall could lead to localized flooding, especially near major roadways like Interstate 10.
According to the National Weather Service, showers and thunderstorms will likely develop after 11 a.m. Wednesday, with a flood watch in effect through the night. Winds will shift from the south at 5 to 8 mph to the west in the afternoon, increasing the risk of sudden heavy downpours.
The chance of storms remains high Wednesday night with scattered showers continuing into Thursday. Tucson International Airport reported clear conditions early Tuesday but this wet pattern signals a shift. Drivers on I-10 and other key routes should watch for water pooling on roads and slow down accordingly. Residents are advised to avoid non-essential travel during heavy storms and secure outdoor items that could be blown around by gusty winds.
Looking ahead, the storm chances continue through the weekend with a 40% chance Friday and Saturday, and thunderstorms likely into Monday. High temperatures will hover around the upper 90s to low 100s, typical for mid-July but with added moisture raising heat indices.
Stay alert for updated warnings through the week. This summer weather alert signals a break from Tucson’s dry heat but demands caution on area roadways and during outdoor activities.
