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. |

Synopsis for puerto rico and the uS. Virgin islands waters... A northerly swell and fresh to strong winds from high pressure in the central atlantic will continue across the local and regional waters over the next several days, resulting in hazardous seas across the atlantic, caribbean and caribbean passages. The worst of the swell is over, and seas will very slowly go back down below small craft advisory criteria on Tuesday and into Wednesday. Quick moving isolated to scattered showers will continue across the local waters.

Area Forecast Discussion National Weather Service San Juan PR 203 PM AST Sun Jan 19 2020
SYNOPSIS. Another area of moisture will move west ahead of what remains of a decaying cold front and bring showers to the U.S. Virgin Islands and Puerto Rico tonight and Monday before drier air moves in from the southeast. This drier air will remain Tuesday and gradually moisten with the approach of a cold front from the northwest late Thursday. A relatively drier weekend is expected to follow.
SHORT TERM. Tonight through Tuesday . The cold front is losing definition over the local Atlantic waters. Skies have become partly cloudy in the vicinity of Puerto Rico and the U.S. Virgin Islands and shower activity has diminished. Another area of moisture ahead of this dying front over the tropical eastern Atlantic will move into Puerto Rico and the U.S. Virgin Islands tonight and Monday with showers increasing over the U.S. Virgin Islands and eastern Puerto Rico this evening. High pressure at 700 mb will move to our northeast which will bring southeast flow at that level and begin affecting the levels below. The surface high over the central Atlantic will move farther to the east allowing winds to gain a considerable southerly component. This will pull drier air over the forecast area Tuesday. Columnar moisture should reach a minimum around 21Z of less than one inch. Showers will decrease considerably, beginning Monday afternoon. On Tuesday there will be sunnier conditions and southeast flow over land will cause the north coast --especially the Greater San Juan Metropolitan area--maximum temperatures to warm 3 to 4 degrees above normal.
LONG TERM. Wednesday through Saturday . /issued 506 AM AST Sun Jan 19 2020/
Guidance continues to show an unsettled pattern during the long-term period as a result of several weak frontal boundaries that is prog to move over the area. The frontal boundaries will increase low- level moisture and instability; this will lead to the development of frequent passing showers as well as gusty winds from time to time. Also, expected cloudy conditions to prevail during this time.
Wednesday, a surface ridge is expected to move northeast ahead of an intensifying mid to upper-level trough over the western Atlantic. The shift in the surface to the mid-level ridge will result in low- level convergence and weak upper-level divergence across the region. Guidance continues to put a vigorous low-level jet with winds ranging from 60 to 90 kts across Puerto Rio and the U.S Virgin Islands throughout the entire long-term period. The instability created by veering southerly winds, jet interaction, troughiness aloft, and increasing moisture will aid in the development of frequent showers across the region during the afternoon through late Wednesday. However, the GFS has a precipitable water value of 1.0 inches early Wednesday, and increasing through the day. The drier air could delay the start of the rain on Wednesday.
Thursday, the GFS shows an area of high pressure moving off the eastern seaboard into the western Atlantic waters, this will cause the surface ridge to the northeast of Puerto Rio to continue to shift away from the area. Also, the frontal boundary to our northwest will strengthen and move closer to the region. Guidance shows a pre-frontal boundary move over Puerto Rico Thursday afternoon. The boundary and its associated moisture will induce frequent showers across the U.S. Virgin Island and Puerto Rico throughout the day on Thursday.
Friday, the GFS holds the pre-frontal boundary over the area with the highest moisture draped across the Caribbean waters. Nevertheless, frequent passing showers will develop across Puerto Rio and adjacent Islands.
Saturday and Sunday, the front is progged to move over Puerto Rio finally. The frontal boundary moving over the area will result in frequent passing showers over Puerto Rico and adjacent Islands. Sunday, the frontal boundary is expected to become diffuse and lose it
AVIATION. Prevailing VFR durg forecast prd. The proximity of a frontal boundary will bring -SHRA/SHRA ovr local Atlantic waters and ovr coastal sections of the islands til 20/03z. Sfc wnds fm SSE btw 10-20 kt with hir gusts btw 25-30 kts nr SHRA and along coastal areas. Max winds WNW 60-70 kt btwn FL380-480.
MARINE. Seas at bouy 41043 peaked at just below 17 feet but are now oscillating between 14 and 16 feet. Seas at buoy 41053, our inner buoy, peaked at 13 feet and dropped to just above 11 feet. Seas may increase again during the evening, but are expected to gradually subside, until seas of all marine zones are below 7 feet by 8 PM AST Tuesday. Seas in the Atlantic and Caribbean are expected to become hazardous again Thursday evening when a northwest swell enters the forecast area.
