MIAMI (AP) — Tropical Storm Ileana formed off Mexico’s Pacific coast on Thursday, the National Hurricane Center said, and was on a forecast track that would take it over or near the resort area of ​​Los Cabos, on the southern tip of the Baja California Peninsula.

Ileana was centered about 240 miles (385 kilometers) southeast of Cabo San Lucas, the Miami-based center said in an afternoon warning. Maximum sustained winds were 40 mph (65 kph) and Ileana was expected to strengthen into the next day.

A tropical storm warning was in effect for parts of the Baja California Peninsula, including Cabo San Lucas and San Jose del Cabo. Forecasters predicted 4 to 6 inches (10 to 15 centimeters) of rain would fall with Ileana, and up to 8 inches (20 centimeters) was possible for coastal areas of Michoacan, Colima and Jalisco states through Friday.

According to the hurricane center, Ileana is expected to move over the state of Baja California Sur on Friday and reach the Gulf of California on Saturday morning.

Tropical Storm Ileana was the only active tropical storm in the National Weather Service’s eastern Pacific basin on Thursday. In the Atlantic basin, post-tropical cyclone Francine caused heavy rainfall in parts of the southern United States and a tropical depression moved over the open sea west of the Cape Verde Islands.
