Weather Brief – Heavy Rainfall Potential / King Tides Outlook – Florida Keys of Monroe County

Locally Heavy Rainfall Potential through Tonight

  • Poor drainage street, parking lot and low lying area flooding is possible during and shortly after any heavy downpours.
  • Those living and/or working in areas prone to frequent rainfall flooding should keep aware of heavy downpours through sunrise Thursday.
  • A COASTAL FLOOD STATEMENT IS IN EFFECT for minor saltwater flooding of low elevation streets and lots.  The risk for rainfall-impacted flooding will be highest during:
  • This morning and again early Thursday morning.
  • The hours of the higher high tide, generally during the mid to late morning hours

Potential Rainfall Amounts

  • The chances for rainfall exceeding 2 inches within 24 hours is expected to be as high as 1-in-2 today, but decrease by Thursday and remaining very low through the weekend.

Outlook for King Tides

  • A non-tropical gale is expected to develop offshore the Mid Atlantic states later this week, then slowly meander near coastal New England, possibly as a non-tropical storm, this weekend.  A long fetch of north to northeast winds down along the entire eastern U.S. will likely lead to tides gradually rising along both sides (oceanside, and gulfside/bayside/soundside) of the Florida Keys.
  • Coastal Flood Advisories may be required by this weekend and extending into next week.
  • The times of high tides will shift from mid to late morning over the next couple days to both late morning/midday AND late evening/post-midnight hours by this weekend.

The next briefing will be issued around 9:30 am Thursday, but to refocus on the upcoming king tide cycle.
