Boris, now a tropical depression after losing some of its punch, nevertheless was potent enough to prompt evacuations of thousands of inhabitants Wednesday along Mexico's Pacific coast.

The season's second named storm -- downgraded overnight from a tropical storm -- Boris brought "extraordinarily" heavy rains that led disaster officials to evacuate some 16,000 people.

On his Twitter account, the head of Mexico's National Civil Protection office, Luis Felipe Puente, said Boris so far has caused no loss of life, although it continues to carry the risk of potentially lethal flash floods and mudslides.

Officials from the US National Hurricane Center said that at 1500 GMT, Boris was 80 miles (130 kilometers) east of the town of Salina Cruz, with maximum sustained winds of 30 miles (45 kilometers) per hour.

It was moving north at two miles (four kilometers) per hour, a leisurely pace ensuring it will linger, continuing to dump up to another 10 inches of heavy rain in some areas, including the states of Oaxaca, Chiapas, Veracruz and Tabasco, the Miami-based NHC said.

The storm comes on the heels of bad weather that already drenched part of Mexico and Guatemala over the weekend.

The remnants of Hurricane Amanda were blamed last week for three deaths in Mexico's Guerrero and Michoacan states.

Weekend rainstorms produced a landslide that killed five people Saturday along Guatemala's border with Mexico.

That country's national disaster relief agency said as many as 100,000 people there have been affected by stormy weather that caused damage to homes and roads. Schools also have been closed in parts of Guatemala.
