PHOENIX – A surge of tropical moisture could bring higher humidity values and waves of rainfall late in the week through the weekend to portions of the Desert Southwest as Tropical Storm Lorena falls apart over northwestern Mexico .

The tropical storm, currently off the west coast of central Mexico , is expected to strengthen into a hurricane before making landfall along the California Baja Peninsula.

The moisture plume from the storm’s future remnants is expected to stream northward, meaning that communities in southern Arizona , New Mexico and West Texas could be subject to enhanced rainfall chances.

Computer models vary on the amount of expected precipitation, but the heaviest totals are most likely to fall along and south of the Interstate 10 corridor.
