Hurricane Rosa weakens rapidly off Mexico

Hurricane Rosa weakens rapidly off Mexico

"Coastal areas are expected to received 0.25" to 0.50" of rain Tuesday into Wednesday, said Brandt Maxwell, a weather service forecaster.

Rosa still had maximum sustained winds of 85 mph (140 kph) early Sunday and it was centered about 355 miles (570 kilometers) southwest of Punta Eugenia in Mexico.

Hurricane Rosa weakened slightly but was still a major hurricane Friday as as it churned toward the Mexican coast, the National Hurricane Center said. Some isolated areas might receive more.

Previously a powerful Category 4 hurricane with sustained winds of 140 miles per hour, Rosa weakened over the weekend and is expected to bring potentially heavy rain, blustery winds and thunderstorms to the Valley from Sunday through Tuesday, forecasters said.

There is increasing confidence that high-grade tropical moisture from Hurricane Rosa may drift into northwest Arizona, southern Nevada and southeast California by Monday morning.

In the south, surf generated by the cyclone off Mexico is expected to build overnight, followed by rain on Monday as Rosa's moisture expands northward from Baja California.

Forecasts call for heavy rainfall in the watch areas, which include Phoenix, Las Vegas and Salt Lake City, with possible flooding in slot canyons and normally dry washes and a potential for debris flows from recent wildfire burn scars.

The National Oceanic and Atmospheric Administration said Hurricane Rosa will weaken over the weekend, but its remnants could bring heavy rainfall to the southwestern United States early next week.
