The National Weather Service has announced flash flood watches for the Southwest United States and a tropical storm warning for northwest Mexico as Hurricane Rosa churns closer.
According to the National Hurricane Center, Rosa is weakening but is still expected to be a tropical storm when it hits the Baja California Peninsula and Mexico’s Sonora state on Monday.
As of Sunday afternoon, Rosa had maximum sustained winds of 120 kilometers per hour as it headed north at about 20 kph.
Weather forecasters predict heavy rains and thunderstorms for the watch areas, which include the U.S. cities of Las Vegas, Phoenix and Salt Lake City. Outer bands of the storm are also expected to bring much-needed rain to coastal Southern California.
Meanwhile, Hurricane Sergio continues to gain strength in the Atlantic but currently poses no threat to land.
