With hurricane season officially under way, meteorologists are already following an area of unstable weather in the southern Gulf of Mexico that was moving north Monday night.
Forecasters said the chance of a tropical storm forming is about 30 percent.
The National Hurricane Center reported in its 8 p.m. update that the system's circulation became better defined Monday and "additional gradual development is possible during the next couple of days despite marginally favorable environmental conditions."
Forecasters said no matter what happens, portions of the Yucatan Peninsula and Cuba are likely to see heavy rains from the system, and Florida could be next.
The bay area is already expected to see heavy rain in the coming days, with the potential for storms throughout the week.
"There's enough moisture in the atmosphere that areas that see rain could get several inches of rain every day," said Josh Linker, a meteorologist with Bay News 9.
