Hurricane Genevieve fizzled after hammering Mexico’s Baja Peninsula, but its remnant moisture and spin may boost thunderstorms in the Desert Southwest and fire-ravaged California through Monday.

Genevieve rapidly intensified to a Category 4 hurricane Tuesday, then grazed Mexico’s southern Baja California Peninsula as a weaker hurricane with flooding rain, high winds and high surf.

After that, as most hurricanes in this part of the eastern Pacific do when they move farther northwest over cooler water and more stable air, Genevieve fizzled rapidly into a remnant low west of the Baja Peninsula.
