The 2011 Atlantic tropical storm and hurricane season is now underway with the first tropical storm of the season forming in the southwestern Gulf of Mexico. Tropical storm Arlene formed around 450km east-southeast of Tampico, Mexico after an area of showers and thunderstorms developed sufficiently to be classified as a tropical storm straight away (skipping the need to be denoted a tropical depression).
Tropical storm Arlene currently sits around 300km off the Mexican coast, moving west-northwest at 11km/h. Maximum sustained winds are 40mph but Arlene is forecast to strengthen significantly before making landfall on the Mexican coast. It’s unclear how much Arlene will strengthen but early forecasts show her coming ashore with 60mph sustained winds.
No threat to the U.S. coastline, tropical storm Arlene is likely to drench parts of northeastern Mexico with heavy rain and strong winds on Wednesday night or early Thursday after making landfall. Arlene is expected to produce rainfall accumulations of 4 to 8 inches with isolated amounts of as much as 15 inches over mountainous terrain, meaning the risks of flash flooding and mudslides will be high.
