Tropical Depression Boris Weakens as It Soaks Mexico

(Corrects classification of Boris in headline, first paragraph.)

Tropical Storm Boris weakened to become a depression and will continue to soak eastern Mexico today, threatening the southern part of the country with heavy rain and floods, according to the U.S. National Hurricane Center.

The system was 85 miles (140 kilometers) east of Salina Cruz, Mexico, as of 2 a.m. Pacific time today, moving north at 5 miles per hour with maximum sustained winds of 35 mph, the center said in an advisory on its website. Boris is expected to drop as much as 20 inches (51 centimeters) of rain in the region, soaking southeastern parts of Mexico especially over higher terrain.

“The primary threat from Boris continues to be very heavy rainfall and the resultant flooding over southeastern Mexico during the next couple of days,” Daniel Brown, a warning-coordination meteorologist at the hurricane center in Miami, said in a forecast analysis.

The depression will move inland slowly, so the area may be drenched for days, according to the center. A tropical depression has maximum sustained wind surface speeds of 38 mph, while a tropical storm has winds speeds as high as 73 mph, according to the center.

Mexico’s government has discontinued all tropical storm warnings. State-run Petroleos Mexicanos has an oil refinery in the port city, with a capacity of 330,000 barrels a day. As much as 8.5 inches of rain has been reported in city of Tonala on the coast of the state of Chiapas during the past several hours, according to the center.

Boris was the second tropical storm of the Eastern Pacific hurricane season, which began May 15. Amanda strengthened into a Category 4 major hurricane without directly threatening land.

The U.S. center is also tracking a disturbance in the Bay of Campeche in the southern Gulf of Mexico. It has a 10 percent chance of becoming a tropical system in the next five days.
