Tropical Storm Boris Forms Off Mexico’s Pacific Coast
Tropical Storm Boris will go ashore on Mexico’s Pacific coast tomorrow, threatening the southern part of the country with heavy rain and “life-threatening” floods, the National Hurricane Center said.
The system was 90 miles (145 kilometers) southeast of Salina Cruz, Mexico, as of 8 p.m. New York time, moving north at 5 mph with maximum sustained winds of 40 mph, the U.S. center said in an advisory. Boris, already pouring rain over southeastern Mexico, is expected to drop 10 to 20 inches (25 to 50 centimeters) in the region, with some mountain areas getting 30 inches.
“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 center in Miami, said in a forecast analysis.
The storm will move inland slowly, so rain may soak the area for days. Puerto Chiapas, Mexico, had received 3.8 inches by midday, the hurricane center said. Mexico’s state-run oil company, Petroleos Mexicanos, has a refinery in Salina Cruz with a capacity of 330,000 barrels a day.
Heavy rain is also predicted in Guatemala, where the meteorological institute warned mudslides are likely because the ground is so saturated it can’t hold more.
“They are going to get hammered with quite a bit of rain,” said Brian Wimer, an expert senior meteorologist at AccuWeather Inc. in State College, Pennsylvania. “This is a classic setup with rain coming in, and once you get away from the coast there are some pretty high mountains, and that helps enhance the rainfall.”
Boris is expected to weaken as it moves ashore, then break apart in the mountains later this week, the center said.
Wimer said there’s a slight chance the remnants of the storm will enter the Bay of Campeche in the Gulf of Mexico. He doesn’t think it will re-form into a storm there.
“It doesn’t look like a great setup but it is something to keep an eye on,” Wimer said.
A tropical storm warning is in place from Salina Cruz, Mexico, to the border with Guatemala.
Boris is the second tropical storm of the Eastern Pacific hurricane season, which began May 15. Storm Amanda grew into a Category 4 major hurricane without directly threatening land.
The hurricane center is also tracking a disturbance in the Bay of Campeche, in the southern Gulf of Mexico. It has a 20 percent chance of growing into a tropical system in the next five days.
