Tropical Storm Beatriz has formed off Mexico’s southern Pacific coast and is forecast to strengthen into a hurricane by late on Friday as it threatens the southwestern hip of Mexico.
Beatriz was about 100 miles south-southwest of Acapulco late on Thursday and moving to the west-northwest at 12mph, with maximum sustained winds of 40mph, the US National Hurricane Centre said.
A hurricane warning is in effect from Zihuatanejo to Playa Perula.
The storm is expected to slow its forward movement over the weekend and dump heavy rain as it scrapes along several southern Mexican states.
Meanwhile, Hurricane Adrian continued to spin away from land into the open Pacific.
Late on Thursday it was about 440 miles south-southwest of the southern tip of Baja California and moving north-west at 8mph.
Its maximum sustained winds strengthened to 90mph but the storm posed no threat to land.
