Hurricane Flossie strengthened to a Category 2 cyclone Tuesday morning off the Pacific coast of Mexico, forecasters said. The National Hurricane Center said Flossie had maximum sustained winds at 100 mph (155 kph) and that rain was falling over parts of coastal Mexico.

A sixth named storm has formed just six weeks into the eastern Pacific hurricane season. Tropical Storm Flossie materialized over the weekend about 400 miles west of Nicaragua, and could skim along Mexico’s west coast before bringing wet weather to the Baja Peninsula late in the week.
