Marine Weather and Tides
Version 3.4 |
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Key West FL 1017 AM EST Sun Jan 19 2020
DISCUSSION. Mostly sunny skies were observed over most of the Florida Keys save boughts of stratocumulus over portions of the Lower Keys, aided by a weak warm advection pattern occasionally saturating the lower troposphere beneath a 4.5C temperature inversion at 9000 ft. Temperatures were a bit a warmer than same time yesterday, entering the upper 70s with dewpoints in the 65-68F range. Winds have gradually become southeast this morning with speeds 5 to 10 mph over the islands, and near or a bit above 10 knots along the reef.
For the remainder of the afternoon, trapped moisture beneath the inversion from shallow buoyancy over the Straits will be weakly focused along the confluent zone north of Cuba, and gradually eroding into the afternoon. An earlier perhaps pessimistic public forecast update was made to account for boughts of cloudiness although measureable rain chances remain generally 10 percent or less for the rest of today.
MARINE. No watches, warnings or advisories are currently in effect for the Florida Keys coastal waters. Southeast winds will gradually become south and decrease further into this evening. However, a cold front expected to pass through the Keys during the day Monday will bring strong northerly breezes, which will last through Tuesday and Wednesday. An addtional freshening of east breezes may occur later Thursday as strong ridging builds southeast across Virginia and the western Atlantic.
AVIATION. VFR conditions are expected to prevail at the Key West and Marathon terminals through tonight. Latest radar images show a few showers south of the Lower Keys that may bring light precipitation to the Key West terminal late morning into early afternoon. Winds SE near 10 knots, decreasing to near 5 knots tonight. A cold front will move across the island chain tomorrow morning, causing winds to become more northerly. A few showers are likely along the frontal boundary.
CLIMATE. On this date in 1997, the daily record low temperature of 48 degrees was last recorded in Key West. Temperature records date back to 1872.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
