Hurricane Hilary in the Pacific
Hilary gained tropical storm status Wednesday morning and continued to pick up steam in the eastern Pacific. Throughout the day on Thursday, the storm gradually strengthened and became a major hurricane.
“Within only 24 hours, Hilary went from a tropical storm to a Category 4 hurricane,” said Rob Davis, a meteorologist at The Weather Network.
Forecasters at the U.S. National Hurricane Center (NHC) say the hurricane is not forecast to make landfall, but could still bring heavy rain to parts of Mexico.
Government officials have issued tropical storm watches and warnings which stretch from west of Acapulco to Punta San Telmo. Up to 130 mm of rain is expected to fall across southern Mexico, with locally higher amounts possible.
Dangerous swells are also affecting parts of the coast and could cause life-threatening surf and rip current conditions.

Meanwhile, Mexico's weather commission predicted 14 named storms for the Pacific.
