New DISCUSSION, MARINE, AVIATION
KEY MESSAGES
- An approaching new moon will result in increasing high tides.
Minor coastal flooding will be possible along the length of the Florida Keys. Moderate coastal flooding may be possible through the first half of next week as this tidal cycle peaks.
- Rain chances will be near to below normal through the weekend.
- Drier conditions are possible as dew points potentially slip to near 70 degrees this weekend.
DISCUSSION
Issued at 912 PM EST Fri Nov 6 2026 A mostly quiet evening with an almost cloud free sky and a shower-free KBYX radar. Temperatures across the island chain are in the upper 70s with dew points in the lower 70s making for a nice pleasant night. Tonight's 00z sounding showed a dry profile with 1.25 inches of PWAT which according to SPC Climatology is just above the 25th percentile for the date. Along the Reef, winds are north to northeasterly at 5 to 10 knots. A Coastal Flood Statement is in effect for the entire island chain as an approaching new moon will result in increasing high tides. For the remainder of the night going into tomorrow not much is expected to change continuing on with the light to gentle breezes and low rain chances. No changes were needed for this update package.
MARINE
Issued at 912 PM EST Fri Nov 6 2026 A Coastal Flood Statement is in effect for the entire island chain. Elsewhere, no watches, warnings, or advisories are in effect.
