Hurricane Rosa, packing Category 3 winds, moved Friday off Mexico's Pacific coast, with forecasters expecting its swells to affect the Southern California surf this weekend.
The storm had maximum sustained winds of 120 mph and was located 625 miles southwest of the southern tip of Baja California as of Friday evening.
"Additional weakening is forecast", the Miami-based agency said, with Rosa expected to become a tropical storm by early Monday as it approaches central and northern Baja California, which adjoins the USA state of California.
A Tropical Storm warning was in effect for the coast of Baja, Ca., from Punta Abreos to Cabo San Quintin.
The latest forecast from the National Hurricane Center (NHC) shows the storm moving west at about 12 miles per hour on Thursday before slowing down and turning to the west-northwest on Friday. It is expected to be a tropical storm when it nears northern portions peninsula on Monday night. The National Hurricane Center said the main hazard is heavy rainfall in Mexico and the American Southwest. Authorities in Barbados said they helped rescue several people from a flooded home and schools were cancelled in the nearby islands of St. Lucia, Dominica, Guadeloupe and Martinique.
There's more rain on the way, but this time it's not from a monsoon storm.
"Coastal areas are expected to received 0.25" to 0.50" of rain Tuesday into Wednesday, said Brandt Maxwell, a weather service forecaster.
