Florida could get doused by rain this week, regardless of whether a tropical system develops near its coast.

The National Hurricane Center is watching the northern half of the state for potential tropical development this week, but forecasters give it a low chance of happening — 20% over the next seven days.

Still, they say a frontal boundary could slow and stall in the area, potentially forming an area of low pressure near north Florida or over the eastern Gulf.

“Some gradual tropical or subtropical development could occur thereafter as the low moves little,” the hurricane center said Monday.

Global storm models show the potential for development, but a relatively low likelihood, hence the 20% figure from the NHC.

“It doesn’t look like it could be much, but with a holiday coming up it could make for a few wet days for parts of Florida,” Jim Cantore of the Weather Channel posted on X.

The rain could arrive by the middle of the week and hang out until the weekend, said the Miami office of the National Weather Service.

“While uncertainty remains, this may result in some threat of flooding for South Florida if persistent rounds of heavy rainfall occur over urban areas. Forecast specifics will likely become more clear as we move forward in time,” forecasters said Sunday.

Over the weekend, the second tropical storm of the season — Barry — sprang up over the coast of Mexico. Like Andrea before it last week, it was a short-lived storm.

The next name on the list is Chantal.
