The approaching Tropical Storm Javier is expected to bring heavy rains and high winds to southwestern Mexico in the coming days, US weather forecasters said.
The latest mudslide in the town of Huauchinango killed at least one person and buried 13 houses under rubble, according to the Puebla state government. A state official yesterday said that up to 10 more people may be missing there.
That was in addition to 10 people who died in mudslides in Coscomatepec, Tequila and Huayacocotla, in a mountainous region of Veracruz state, Governor Javier Duarte said on Twitter.
"On the forecast track, the centre of the tropical cyclone should pass near or over the southwest coast of Mexico later today, and approach the southern portion of the Baja California peninsula on Monday," the centre said.
The storm was packing maximum sustained winds of 45 miles per hour (75 km/h) with higher gusts and was expected to dump four to six inches of rain in western Mexico, it said.
Another tropical storm, Ivette, also was swirling in the eastern Pacific, but it was far from land and expected to weaken later in the day, according to the NHC.
