On Thursday at 4 pm, the National Hurricane Center issued an advisory stating that the weather system had gained sufficient intensity to be named Ileana. The tropical depression had upgraded to a tropical storm with winds of 40 mph. Tropical Storm Ileana is 240 miles south-southeast of Cabo San Lucas Mexico, with maximum sustained wind of 40 mph. It’s moving 9 mph to the north-northwest.

“A turn to the north at a slightly slower forward speed is expected Friday night.” meteorologists state. “On the forecast track, the center of Ileana should pass near or over the southern portion of Baja California Sur Friday and Friday night before emerging over the southern Gulf of California late Friday night or early Saturday.” They also said “Some strengthening is expected during the next 24 hours until Ileana reaches Baja California Sur.”

The system, which has been named Ileana, has become a tropical storm with sustained winds of 40 mph after undergoing intensification from a tropical depression.

HAZARDS AFFECTING LAND:

RAINFALL: Tropical Storm Ileana is expected to produce 4-6 inches with localized higher amounts up to 8 inches across the coastal areas of Michoacan, Colima, and Jalisco through early Friday. From Friday through Sunday, Tropical Storm Ileana may result in 4-6 inches, with localized higher amounts up to 8 inches, across southern Baja California. For northwest coastal Sinaloa, Tropical Storm Ileana may produce between 6-8 inches with localized higher amounts up to 12 inches. This heavy rainfall will bring a risk of flash flooding and mudslides to portions of the area.

WIND: Tropical storm conditions are expected to first reach the coast of the southern Baja California Peninsula within the warning area Friday morning, making outside preparations difficult or dangerous. Tropical storm conditions are possible within the watch area by early Saturday.

SURF: Swells generated by Tropical Storm Ileana will affect portions of the coast of west-central Mexico during the next day or so, and will spread northward along the coasts of the southern Baja California Peninsula and mainland Mexico beginning tonight. These swells are likely to cause life-threatening surf and rip current conditions.
