Emergency crews worked Sunday to find shelter for 50,000 people left homeless after two tropical storms whipped through coastal areas of both eastern and western Mexico, killing at least 10 people, authorities said.

Rain from the storms continued to drench parts of the country and many areas were without power or communications.Mud and rock loosened from hillsides by the days of rain blocked numerous roads, officials in several states said.

"There is a lot of damage and at least eight neighborhoods are badly hurt," Javier del Porte, a public works official, said by telephone from Tapachula in the southernmost state of Chiapas on the Pacific coast.

Authorities said 30,000 were forced to flee their homes after Hurricane Debby, subsequently downgraded to tropical storm status, hit the Gulf of Mexico coast on Friday.

Most of the evacutions were in the state of Veracruz, state government spokesman Raul Torres said. Three people died when mudslides crushed two houses in Papantla, 16 miles from the Gulf of Mexico, and three storm-related deaths were reported in Poza Rica, he said.

Four others perished and 16 were injured when a mudslide crushed three houses in the mountain community of Ixtlahuaco, about 100 miles northeast of Mexico City.

About 20,000 people were evacuated Saturday in Chiapas to avoid the brunt of tropical storm Kristy, according to the government news agency Notimex.

Debby was the first hurricane of the 1988 Atlantic hurricane season and the fourth storm to be named.
