Marine Conditions:

The Caribbean Sea

There are two tropical waves in the Atlantic, and one in the Caribbean.

The eastern extension of the E Pacific monsoon trough and abundant moisture results in scattered moderate to isolated strong convection within 130 nm of the coast of Nicaragua, Costa Rica, Panama and NW Colombia. The rest of the Caribbean is dominated by a fairly dry weather pattern.

A modest north-south pressure gradient persists in the south-central Caribbean between a broad Colombian Low and weak ridging north of the basin. Recent scatterometer satellite data indicate that fresh to strong trades are occurring within 200 nm of the north coast of Colombia and 70 nm of the coast of NW Venezuela, encompassing the Gulf of Venezuela and the waters surrounding the ABC islands. Gentle to moderate trades prevail elsewhere. Seas are 4-6 ft over the south-central Caribbean and 2-4 ft elsewhere.

Looking ahead, Hurricane Sam is near 13.8N 49.7W 943 mb at 5 AM EDT moving WNW at 7 kt. Maximum sustained winds 125 kt gusts 150 kt. Sam will move to 14.3N 50.6W this afternoon, 15.0N 51.8W Mon morning, 15.8N 52.9W Mon afternoon, 16.6N 53.9W Tue morning, 17.5N 55.0W Tue afternoon, and 18.4N 56.3W Wed morning. Sam will change little in intensity as it moves to 20.8N 59.3W by early Thu. Meanwhile, moderate trade winds will persist over much of the Caribbean into early next week. Fresh winds will prevail over the south-central Caribbean as high pressure builds east of the Bahamas through midweek.

At 5 a.m. AST, the center of Hurricane Sam was located over the tropical Atlantic Ocean about 940 miles (1510 km) east-southeast of the northern Leeward Islands. Sam is moving toward the west-northwest near 8 mph (13 km/h). This general motion is expected to continue today, followed by a turn toward the northwest on Monday. Then, a northwestward motion is forecast to continue through midweek.

Maximum sustained winds are near 145 mph (230 km/h) with higher gusts - a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. The estimated minimum central pressure is 943 mb (27.85 inches). Sam is a small hurricane. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km). Some fluctuations in intensity are expected to occur during the next day or so. Thereafter, some slow weakening is forecast.

An elongated area of disorganized showers and thunderstorms associated with the remnants of Peter is located several hundred miles south-southeast of Bermuda. Upper-level winds only appear marginally conducive for some slow development of this disturbance over the next few days as it moves northeastward at about 10 mph.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

A tropical wave is expected to move off the west coast of Africa on Monday. Environmental conditions are forecast to be conducive for gradual development thereafter, and a tropical depression could form by midweek while the system moves westward to west-northwestward at 10 to 15 mph over the far eastern tropical Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...60 percent.

A broad area of low pressure could form over the eastern or central tropical Atlantic early this week, to the west of the tropical wave that will be moving off the coast of Africa. Thereafter, environmental conditions could support some development of this disturbance while it moves westward at 5 to 10 mph through the middle of the week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...30 percent.

Fairly steady easterly Caribbean winds, but full of small isolated rain showers.
A lot of cloud developing over Honduras, which could come our way over the next day or two. Not much indication of high level movement, but some is causing some clashing, causing rain.

Looks as if today will be mainly cloudy with a fair bit of sunshine, but could be rain anywhere at any time.
