Tropical Storm Karl got a little stronger on Wednesday morning in the southern Gulf of Mexico.

Karl is no threat to the U.S. but is expected to bring heavy rain to parts of Mexico’s Gulf Coast over the next few days, according to the National Hurricane Center.

Landfall is expected on Friday in Mexico, and a tropical storm watch remains in effect for part of the coast there from Tuxpan to Frontera.

As of 10 a.m. CDT Wednesday, the center of Tropical Storm Karl was located about 200 miles north-northeast of Veracruz, Mexico, and was drifting north at 3 mph.

Karl had 45 mph winds, making it a minimal tropical storm.

The hurricane center expects Karl to drift a bit today before picking up speed and turning to the southwest toward Mexico. The storm will be approaching the coast by Friday, which is later than originally forecast.

The hurricane center said little change in strength is expected, and Karl is not forecast to become a hurricane. Weakening could begin on Thursday.

The storm is expected to bring a threat for flooding to Mexico. The hurricane center said 3 to 7 inches of rain with local amounts of 12 inches will be possible in Veracruz and Tabasco states in Mexico through Friday night.

There were no other areas being watched for development in the Atlantic as of Wednesday.

The Atlantic hurricane season ends on Nov. 30.
