Small Craft Exercise Caution headlines and Small Craft Advisories may be required for portions of the local marine zones. - A moderate drought continues for the entire island chain. Burn bans are possible, trees and bushes begin browning, and water supply decreases. For the upcoming week, there will be a slight chance for showers. && .AVIATION... (18Z TAFS) Issued at 1245 PM EST Mon Mar 2 2026 Although a passing shower cannot be ruled out in the vicinity of the terminals, VFR conditions will prevail through 18z Tuesday afternoon, with just passing FEW-SCT low clouds based at around 015-025. Near- surface winds will remain generally out of the northeast to east at 9 to 11 knots. && .MARINE... Issued at 1104 AM EST Mon Mar 2 2026 There are no watches, warnings, or advisories for the Florida Keys local waters. A large and robust high centered over the northeastern U.S. will dive southeastward off of the coast, and into the North Atlantic over the course of this afternoon. This will usher in a prolonged period of moderate to fresh breezes across the Florida Keys marine zones for the next several days, as the center of the high becomes stationary over the central North Atlantic. Small Craft Exercise Caution headlines and Small Craft Advisories may be required for portions of the local marine zones. && .PREV DISCUSSION... Issued at 436 AM EST Mon Mar 2 2026 An expansive area of high pressure centered over the northeastern U.S. will track southeastward today, and emerge over the North Atlantic. While the high is expected to sit over the ocean through the rest of the week, the result will be an extensive period of relatively unremarkable weather for the Florida Keys. Persistent easterly breezes will contribute to occasional moisture surges, so some shower activity will be possible on virtually any day. However, this set up isnt one that offers widespread washout conditions, but rather pop up showers that could develop anywhere in the area. Even with the benign pattern, breezes will wax and wane through the week, and peak during the overnight hours. Both deterministic and ensemble guidance suggest that breezy conditions will prevail through the week, and marine hazard headlines may be required during some of the overnight periods. && .PRELIMINARY POINT TEMPS/POPS...
