Tropical storm Manuel has surged to hurricane strength off Mexico's Pacific coast, with the potential to strengthen before crashing ashore in a country already reeling from deadly storms, the US National Hurricane Center says.
Packing top sustained winds of almost 115 kilometres per hour, "some slight strengthening is possible before the hurricane moves inland," the Miami-based NHC warned on Wednesday.
The storm was about 20 miles southwest of Altata, Mexico, moving north at a speed of seven kilometres per hour, the NHC said.
Heavy rains from the system could cause "life-threatening flash floods and mudslides" in Sinaloa, Nayarit and southern Baja California states, the NHC warned.
