(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxca62 tjsj 201513 afdsju area forecast discussion national weather service san juan pr 1113 am ast Wed feb 20 2019 Update An area of low level clouds and showers embedded on the trade winds will continue to move across the u.S. Virgin islands and puerto rico through the afternoon hours. This rainfall activity should result in mostly minor rainfall amounts across the islands. Breezy conditions will continue through Thursday under a 15-25 kt east-northeast wind flow. Day time temperatures should range in the low to mid 70s across the higher elevations and under the mid 80s across coastal areas. Otherwise, no change from previous forecast. Aviation MainlyVFR conditions expected to prevail. However, trade wind showers and sct-bkn CIGS btw fl030-fl060 will continue across tist and the pr terminals through at least 22z. Latest 12z tjsj upper air sounding indicated east-northeast winds around 20 kt blo fl030. Marine Coastal buoys were indicating seas between 3-5 feet and east winds between 15-20 knots. Winds will gradually continue to increase through Thursday and this will create hazardous seas across most of the regional waters, seas are expected to increase between 6-8 feet and small craft advisories are in effect. Please refer to latest mariner weather message (mwwsju) for more information. Prev discussion issued 657 am ast Wed feb 20 2019 Synopsis Cloudy conditions with passing showers will affect portions of the islands throughout the day. However, a mid to upper level ridge will promote stable weather conditions across the region. A surface high pressure moving north of the region across the atlantic waters will result in breezy trade winds through at least Friday. Short term... Today through Friday... mid to upper-level ridge will continue to yield stable weather conditions aloft and a robust inversion between the 700 and 775 mb layer. This will prevent the development of deep convection and therefore heavy rainfall activity through the period. However, just enough low-level moisture will be present to result some light to moderate trade wind showers across the area through the end of the week. For today, a patch of low-level moisture will move across the area. This will result in periods of brief showers affecting the usvi and eastern portions of pr during the morning hours followed by additional activity during the afternoon hours, mainly over eastern pr. Less shower activity is expected on Thursday as drier air in the low-levels moves overhead. Another round of trade wind showers is expected on Friday as a band of higher low-level moisture, in association with the remnants of a frontal boundary, moves over the area. Once again, most of the shower activity is expected to be concentrated across the eastern half of pr and the usvi. Rainfall accumulations for the most part should remain light with some minor ponding of water on roadways possible. Windy conditions are also expected through the period. Strong surface high pressure moving off the east coast of the united states and across the western atlantic will result in a tightening of the local pressure gradient. This will result in winds ranging between 15 and 25 mph with higher gusts, especially near showers. Highest winds are expected from the mid morning through early evening hours |
each day. Long term... Saturday through Thursday... forecast soundings continues to suggest dry air at mid levels, but enough low level moisture to result in trade wind showers from time to time. Although a stable weather pattern will persist during the long term, model guidance suggested an increase of low level moisture and wind surface convergence late in the forecast period. If this pattern holds, frequent patches of clouds and quick passing showers could be expected Tuesday through Thursday. However, confidence is low due to the amount of uncertainty associated with the end of the forecast cycle. Aviation... mainlyVFR conditions are expected across the terminals throughout the period. Vcsh -shra are possible across tist tisx tjsj terminals through 20 21z, which may result in brief MVFR conditions. A few -shra are also possible across tjmz between 20 16z-22z. Winds will continue from the e-ene around 10 kts through 20 13z, increasing to 15-20 kts with higher gusts, especially near shra, afterwards through 20 22z. Marine... fresh to locally strong trade winds will create rough seas across most of the local waters. Seas will range between 5 and 7 feet across the local waters increasing at 6 to 8 feet by Thursday. Small craft advisories are in effect for the caribbean and atlantic offshore waters as well as across the local passages. Hazardous conditions will diminish over the weekend but some areas will persist with seas of 7 feet through early next week.

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. |
