Tropical Storm Danielle forms off Mexico's eastern coast

The official start of Hurricane Season isn't until a week from Friday, but Tropical Storm Danielle has formed off Mexico's eastern coast, where it's spreading rain.

The U.S. National Hurricane Center in Miami says Danielle's maximum sustained winds Monday morning have increased to near 40 mph with some slight strengthening forecast before the storm makes landfall later in the day.

A tropical storm warning is in effect from Laguna Verde to Rio Panuco.

The storm is centered about 95 miles east-southeast of Tuxpan, Mexico, and is moving west-northwest near 7 mph.

The storm is expected to produce rainfall totals of 6 to 10 inches with isolated areas possibly getting as much as 15 inches in higher terrain over several Mexican states.
