Coastal Flooding Potential
- A COASTAL FLOOD STATEMENT REMAINS IN EFFECT over the Upper Keys for minor saltwater flooding of low elevation streets and lots, primarily along the Bayside.
- Currently tides are running 6 to 8 inches higher than lunar/astronomical tide prediction charts indicate.
- Minor saltwater flooding is expected to increase for both high tides (each day) and expand throughout the entire island chain by this weekend in combination of the full moon phase and effects from a large non-tropical low pressure system (“Nor’easter”) containing storm force winds evolving offshore the Mid-Atlantic States.
- Eventually the higher high tide will transition to the late evening/early pre-dawn hours early next week.
- Tides may eventually reach around 1 foot above normal predicted values, and Coastal Flood Advisories may be required either Sunday night or Monday night.
- If Coastal Flood Advisories are issued, the peak tides could reach between 6 and 12 inches deep in the lowest streets and lots in areas prone to King Tide flooding.
Rainfall Outlook
The chances for rainfall exceeding one inch per day will be very low (10% or less) throughout the weekend through Tuesday of next week, then increase to about 25% by Wednesday. Therefore combined rainfall with King Tide impacts are not expected through at least early next week.
