Surface high pressure will remain anchored across the west and central atlantic through the weekend to maintain moderate east to southeast trade winds. However, the chance for showers and thunderstorms will increase across the region late Sunday and Monday as a tropical wave is forecast to enter and move across the eastern caribbean. Short term Rest of today through Sunday... ridge pattern aloft will dominate the local weather conditions over the next few days to maintain overall stable conditions across the region. Limited moisture availability and subsidence aloft will inhibit significant development of showers and thunderstorms across the islands through at least Sunday. However... There will be sufficient moisture convergence and diurnal effects to allow for afternoon convection today and over the weekend. Showers and isolated thunderstorms will remain possible mainly over parts of the interior and west sections of puerto rico, as well as in and around parts of the san juan metro area, where streamer-like showers will be likely. The remainder of the islands should experience mostly sunny skies with only a few afternoon showers mainly on the downwind side of the islands. The prevailing easterly winds will continue to transport patches of low level moisture across the region and bring a few showers to the windward side of the islands... Especially overnight and during the early morning hours. Winds are expected to become more southeasterly by Saturday, when afternoon showers should be focused over northwest pr. For Sunday... Conditions should be somewhat drier ahead of the tropical wave expected on Monday, but will not rule out the chance of afternoon showers. Long term Monday through Saturday... increasing moisture with showers and thunderstorm activity is expected on Monday, as a tropical wave will enter and move across the eastern caribbean. This feature is expected to interact with a mid to upper level trough tutt which will relocate just northeast of the |
islands. As a result expect periods of enhanced convection across portions of the islands and coastal waters through Monday. This will be followed by a gradual decrease in shower activity on Tuesday and Wednesday. Another tropical wave is forecast to reach the forecast area on Thursday. This feature will again increase local moisture convergence which should then persist across the forecast area through Saturday. Good moisture convergence and the proximity of a tutt low will therefore maintain a moist and unstable weather pattern during the latter part of next week through Saturday. Stay tuned as we will continue to monitor and see how this pattern unfolds. Aviation Vfr conds entire fcst prd.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. |
