A brewing tropical system in North Florida prompts flood watch in South Florida
South Florida could see some street flooding Monday and Tuesday, thanks to a potential tropical system brewing near the north end of the state.
The Miami office of the National Weather Service called for a flood watch — when there’s a chance of flooding but it’s not yet happening — for Monday afternoon and Tuesday in urban southeast Florida.
“Regardless of how the disturbance evolves, widespread 1-3” of rain are expected across South Florida between today and Thursday morning, with a reasonable worst case scenario for isolated locations of 5-7” or more,” the NWS said early Monday.
The heaviest of those rains are expected Monday afternoon through late evening.
The moisture sparking all that rain is attached to a low-pressure system drifting off the northeast coast of Florida this weekend. The National Hurricane Center predicts it will cross the state in the next day or so and form in the Gulf around Tuesday — potentially as a tropical depression.
As of Monday afternoon, the NHC gave the system a 30% chance of developing in the next seven days and a 20% chance of strengthening in the next day, a slight uptick from earlier in the day.
For now, weather models continue to show the system developing into a weak and broad depression toting plenty of rain.
“The amount of development will probably depend on how far offshore it stays,” Andy Hazelton, an associate scientist at the University of Miami, posted on X. “I think it’s worth keeping an eye on trends for this one..”
A very similar setup last week led to the third named storm of the season, Tropical Storm Chantal, which came ashore in North Carolina with deadly flooding that claimed several lives.
The next name on the list is Dexter.
