Francine tracker: Tropical system forecast to strengthen to hurricane ahead of Louisiana landfall

A tropical system churning in the southern Gulf of Mexico is forecast on Monday to become Tropical Storm Francine as it moves toward a Wednesday landfall in Louisiana, the National Hurricane Center said.

A tropical storm watch has been issued for parts of Texas, with the expectation that hurricane watches could be issued later today for parts of the Gulf Coast.

The storm is forecast Tuesday night into Wednesday morning to significantly strengthen into a Category 1 hurricane with winds near 80 mph.

The storm could then make landfall in western Louisiana late Wednesday afternoon or early evening, as a possible Category 1 hurricane, weather officials said.

Storm surge, rainfall flooding and hurricane wind gusts are forecast from Port Arthur, Texas, to Lake Charles, Louisiana, officials said.

A foot of rain is forecast for parts of Louisiana, with up to a half a foot in eastern Texas.

Heavy rain with flood threats is expected to spread into New Orleans and north into the Mississippi River Valley and Mid-South, all the way to Jackson, Mississippi, and even into Memphis, Tennessee, by Thursday, officials said.
