A Tropical Depression called Twelve-E off the western coast of Mexico might bring moisture into southeastern ÃÛÁÄÖ±²¥ later this week, the weather service says.
Twelve-E is expected to become Tropical Storm Elena, but its potential impact on Tucson’s weather depends on the path it takes moving north into the Baja region, the N said.

A Tropical Depression moving across northern Mexico is expected to strengthen and could travel close enough to ÃÛÁÄÖ±²¥ to increase rain chances in the region later this week, forecasters said Tuesday.
The storm’s maximum sustained winds Tuesday were near 45 mph.

There’s a slight chance of rain in the region Wednesday, but forecasters are keeping an eye on a tropical depression in Mexico that might boost rain chances here late this week.
The storm was expected to keep strengthening and could become a hurricane by Wednesday, The in Miami said.
Wednesday’s high temperature in Tucson is expected to be 99 degrees with about a 30% chance of rain.
