Sea Surface Temperature (°f): 86
Outlook: For Tuesday and Tuesday night is for a few showers and isolated thunderstorms, mostly south and coast.
Sargassum Forecast from August 17 to August 25: Satellite imagery suggests that sargassum concentration has decreased slightly over the area. However, there is a low to medium chance of additional sargassum mats drifting into the area during the next few days. San Pedro has a medium probability and a moderate impact.
Tropical Weather Outlook: Tropical cyclone formation is not expected in the North Atlantic, the Caribbean Sea or the Gulf of Mexico within the next 48 hours. Click for more of the tropical weather outlook...

Marine Conditions:

The Caribbean Sea

There are three tropical waves in the Atlantic, and two in the Caribbean, and one over the Yucatan Peninsula.

The most recent scatterometer data show fresh to strong winds across the central Caribbean, and in the Gulf of Honduras with seas to 8 ft near the coast of Colombia. Convection across the basin are related to the tropical waves.

The aerial extent of the trade winds will increase over the next 24 hours covering most of the waters S of 17N and E of 80W. As a result, fresh to strong trade winds are expected over the east and central Caribbean through midweek, with building seas of 8 to 10 ft. Fresh to locally strong winds and seas to 8 ft are also expected in the Windward passage through Tue night.

Looking ahead, a broad area of low pressure is forecast to form over the western Caribbean Sea late this week. Environmental conditions are expected to be favorable for gradual development of this system thereafter while it moves west-northwestward over the northwestern Caribbean Sea. The latest Tropical Weather Outlook indicates that this system a low chance of tropical cyclone formation through 5 days.

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

At 5 a.m. EDT, the center of Tropical Depression Henri was located inland about 60 miles (95 km) north-northwest of New York City, New York, and about 90 miles (145 km) west of Hartford, Connecticut. The depression is nearly stationary at the moment, but is expected to begin an eastward motion by later this morning into the afternoon hours.

We are also watching a few tropical waves, either across the tropical Atlantic or emerging off the African coast this week, but development with these seems unlikely for the next few days.

The National Hurricane Center has officially begun to monitor a low-pressure area that could develop in the Caribbean over the next few days.

Tropical waves no. 27 and 28 are in the area. Tropical wave no. 28 is a strong wave and is being watched for formation in the southwestern Caribbean in a few days (see above).

On Ambergris Caye this morning we have a wind from the East at 17 mph and rough sea conditions around our barrier reef. Today's expected high temperature is set at 85.

There has been a very large ITCZ type swellup over the whole of central and southern Belize this morning, causing a huge amount of rain, right across southern and west central Belize, with other showers in the north. That is now moving away into Guatamala with the easterly Caribbean winds. This all being triggered by a lot of high level cloud coming down from the NW.

Today
Looks as if this wet weather will linger around for much of the morning, but not as heavy as earlier, and could still be some showers this afternoon.

Tonight
Probably continuing with its cloud and patches of rain.

Crown Weather:

Northwestern Caribbean Into Gulf Of Mexico Tropical Development Possible Late This Week: A fairly convectively active tropical wave is currently located over the eastern Caribbean where environmental conditions are very unfavorable for development. It is expected that this tropical wave will move westward this week reaching the western Caribbean by about Thursday. It is expected that the environmental conditions will be favorable for development late this week in the western Caribbean and I think that it's quite possible that we'll see tropical development in the area of the northwestern Caribbean as soon as Thursday night or Friday.

The model guidance, including the GFS, Canadian and European model guidance, are in very good agreement with each other in a forecast of northwestern Caribbean tropical development late this week. Where the guidance sort of disagrees is the potential track of this system once it moves into the Gulf of Mexico this weekend.

I think it's quite possible, if not likely that our next named storm will come out of the tropical wave now in the eastern Caribbean when it reaches the northwestern Caribbean late this week. I put the chances of tropical development at 60-plus percent.

The track of this potential system will hinge on the strength and position of an upper level high pressure ridge that will be located over much of the southeastern United States for the next week or so. The western extent of this ridge is going to be very important in determining whether this system will head directly west-northwestward into eastern Mexico or be turned a little to the northwest and thus become a threat to some part of the Texas coast or even some part of the Louisiana coast early next week.

Another factor that's going to be very important is the exact location of where this potential system forms. If it forms in the area from the southwestern Caribbean to near the northern coast of Honduras and coast of Belize, I think it's likely it'd be guided towards a landfall in eastern or northeastern Mexico. On the other hand, if this system forms near the northeastern tip of the Yucatan Peninsula, it could be guided further north in the Gulf of Mexico leading to a potential impact to some part of the Texas coast or the Louisiana coast.

My thinking, at this point, is that the most likely track is for this system to develop near the eastern Yucatan Peninsula by around Friday and then move across the Yucatan Peninsula. From there, I think it's most plausible that this system will bring tropical storm and possibly hurricane impacts to northeastern Mexico and possibly South Texas next Monday.

Additional Gulf Of Mexico Tropical Development Possible Late Next Week & Next Weekend (September 2-September 6): The Gulf of Mexico may really be a spot to watch closely for tropical development for at least the next couple of weeks. Ensemble model guidance of both the GFS and European models have a fairly strong signal that a second tropical system could form in the southern and central Gulf of Mexico during the weekend of September 4-5.

The "seed" of this development seems to be a tropical wave that's now located over the far eastern Tropical Atlantic that ends up in the western Caribbean by the second half of next week. Again, the track of this system will depend on both where exactly it forms and what the upper level pattern looks like. It should be noted that the longer range 3 model ensemble mean guidance seems to hint that there may be a break in the high pressure ridge that would allow this system to head further north leading to a higher threat to the northern or western US Gulf Coast.
