Update: Tropical Storm Arlene

Posted at 7:52 AM ET

arlene-2-smallTropical Storm Arlene made landfall near Cabo Rojo in Mexico’s Veracruz State at around 09:00 UTC earlier today with sustained winds of around 65 mph (100 kmph), equivalent to a strong tropical storm, according to the National Hurricane Center (NHC). Arlene has since moved inland and is currently located around 45 miles (70 kilometers) north-northwest of Tuxpan, Mexico and 45 miles (70 kilometers) south-southeast of Tampico, Mexico. The center of the storm is expected to continue moving inland over mainland Mexico today. Arlene is expected to weaken within the next 24 to 36 hours, and to dissipate by Friday as it moves over the mountains of Central Mexico. The NHC said tropical storm-force winds extend 140 miles (220 kilometers) from the center of the storm.

A tropical storm warning remains in effect for the coast of northeastern Mexico (from Barra de Nautla south to Palma Sola). The NHC said Arlene could produce 4 to 8 inches (100 to 200 millimeters) of rain over the Mexican states of Tamaulipas, Veracruz and eastern San Luis Potosi, with the possibility of 15 inches over mountainous terrain. The NHC warned the heavy rainfall could cause life threatening flash floods and mudslides. A threat of storm surge remains along the immediate coast near and to the north of Cabo Rojo, which could raise water levels by as much as 3 feet (0.9 meters) above normal tide levels.

Veracruz governor Javier Duarte stated there are no major problems, and they expect to be clear of the storm by midday Thursday. Authorities in Tamaulipas, Veracruz and San Luis Potosi took precautions by closing schools, mobilizing emergency medical units and preparing evacuation shelters. Mexico’s navy and army opened 398 shelters and continue to monitor rivers for possible flooding. Mexico’s national weather service reported 6 inches (150 millimeters) of rain had fallen over a 24-hour period in northern Veracruz. Civil protection authorities have reported fallen tree branches and power outages, but the majority of coastal towns have escaped serious damage.

Mexico is a top oil exporter to the United States with almost all of its exports originating in the Gulf of Mexico, yet no major disruptions of Mexican oil production is expected. U.S. oil companies stated Arlene was too far south and too weak to affect operations at U.S. Gulf of Mexico refineries, offshore platforms and drilling rigs.

The Atlantic hurricane season runs from June 1 to November 30. Several forecasters, including AccuWeather, the Colorado State University (CSU), NOAA and Weather Services International (WSI), expect the 2011 hurricane season to see above-average activity.
