Tropical moisture from Hurricane Lorena to fuel flash flood risk for US Southwest

Atmospheric moisture from Hurricane Lorena will surge into the Southwest from Thursday into the weekend. While the heaviest rainfall is expected across Mexico, parts of Arizona and New Mexico could receive a widespread 1-2 inches of rain, with locally higher amounts possible. In these regions, burn scars from past wildfires could elevate the risk of flash flooding, as debris flows may occur.
