Belize Weather Forecast: November 21, 2021

General Situation:
Ambergris Caye: Conditions this morning by Elbert just before or after this post!
Belize NMS: Present Condition: Partly cloudy this morning, large areas of clearing. Partly cloudy in San Pedro. Generally fair weather prevailing.
Advisories: None.
24-hour forecast: Sunny skies today with a few cloudy spells, along with isolated showers or an isolated thunderstorm. Tonight skies will be partly cloudy to clear with little or no rainfall.
Winds: N-NE, 0-5 kts
Sea State: Slight
Waves: 1-3 ft
Sea Surface Temperature (°f): 83
Outlook: (Monday & Monday night) for generally fair weather at first with isolated showers. Then later expect an increase in showers and thunderstorms, developing mainly over northern and inland areas and this will be associated with the approach of a cold front.
Sargassum Forecast from November 16 to November 24: Only small chances of sargassum drifting ashore during the next few days, producing minimal impacts on local beaches across the country. San Pedro has a low probability and a minimal impact.
Tropical Weather Outlook: Tropical cyclone formation is not expected in the North Atlantic, Caribbean Sea or Gulf of Mexico during the next 48 hours. Click for more of the tropical weather outlook...

Marine Conditions:

The Caribbean Sea

Recent scatterometer data show mainly gentle to moderate trade winds across the basin, with the exception of fresh winds near the coast of Colombia and in the Gulf of Venezuela. Seas of 5-7 ft prevail in the south-central Caribbean, with 3-5 ft elsewhere, except in the lee of Cuba and in the Gulf of Honduras where seas of 1-3 ft are found. Seas of 5-6 ft are likely occurring in the Yucatan Channel.

Scattered showers are thunderstorms continue to develop over the Caribbean plains of Nicaragua. A diffluent pattern aloft is helping to sustain this convective activity. A large patch of moisture, with embedded showers, covers the Leeward Islands, the US/UK Virgin Islands and Puerto Rico, and it is moving westward. A well defined swirl of clouds, with some convective activity, is noted on satellite imagery over the eastern Caribbean S of Puerto Rico. This could be related to a surface trough that crossed the Leeward Islands a couple of days ago. Elsewhere, shallow moisture embedded in the trade wind flow will continue to move across the region producing isolated to scattered passing showers.

For the forecast, mainly gentle to moderate trades will prevail across much of the Caribbean Sea through Mon. A cold front will reach the Yucatan Channel by Mon evening, and extend from eastern Cuba to the Gulf of Honduras by late Tue. Fresh to locally strong winds and building seas are expected across the western Caribbean, the Windward Passage and Mona Passage likely through Thu as high pressure builds N of the area in the wake of the front.

There are no disturbances over the Atlantic or eastern Pacific basins that have any potential for tropical cyclone development during the next five days. The hurricane season officially ends on November 30th.

The NE Caribbean winds are actually coming down the east coast of America, almost from New York and presently clashing with the high level winds form the SW and causing a lot of heavy cloud over all Belize this morning, but very little rain, mainly along coastal areas..

Looks as if today will be mainly cloudy all day, perhaps reducing a bit later and the chance of the odd small rain shower.

Temperatures in Belmopan : ( Coast usually cooler, hills even cooler )
Last Night 23°C 73°F Yesterday max. 29°C 84°F Yesterday Rain 0.2 mm ( 0.01") Over Night Rain 0 mm ( 0" )

Present Condition: Mostly cloudy in the far north. Partly cloudy in San Pedro. Mainly fair weather will prevail through today with an increase in moisture expected tomorrow, ahead of an approaching cold front.

24hr Forecast: Cloudy skies with generally isolated showers or periods of light rain mainly over inland areas this afternoon. Then partly cloudy skies with only isolated showers mostly offshore tonight and tomorrow morning.

Outlook: A few showers, periods of rain and isolated thunderstorms starting over northern and inland areas Monday afternoon, spreading over the south by nighttime, decreasing. Then periods of light rain and a few showers over the south coast and offshore Tuesday.

There is, as I suspected, some slow moving cool air, now stopped out at sea. But the clashing with the NE Caribbean air and thigh level, is now resulting in the Rain areas, moving much further inland now.
