A large and complex area of low pressure is expected to develop near the Yucatan Peninsula and the northwestern Caribbean Sea in a couple of days, partially related to the remnants of Tropical Storm Agatha from the eastern Pacific.

Despite strong upper-level winds over the area, this system has a 60% chance of tropical development in the next few days and could become a tropical depression while it moves northeastward over the northwestern Caribbean Sea and southeastern Gulf of Mexico late this week.

Regardless of development, locally heavy rainfall is likely across southern Florida, and the Florida Keys by the end of the week. Forecasters are unsure whether a tropical depression, or a named storm, will form.
