NATIONAL METEOROLOGICAL SERVICE OF BELIZE
The synoptic situation at the start of November placed an Atlantic high pressure ridge over Florida and the southeast Gulf of Mexico to the Yucatan Peninsula. The ridge produced a light east to southeasterly flow for Belize. A cold front extended from a 1004hPa surface low over the Carolinas/Florida to the northwest Gulf of Mexico and southeast Texas. During Saturday (2nd) evening skies turned increasingly cloudy in the north of the country with layered clouds (at mid and upper level).Water vapour channel showed moist air invading southern Mexico/Yucatan Peninsula/Guatemala and Belize. Later,the cold front extended from southern Florida to the Mexican Gulf coast near 20°N.Showers and thunderstorms occurred over northern Belize Sunday (3rd) morning as the cold front reached the Yucatan Peninsula. A continental surface high produced ridging over the western Gulf of Mexico to maintain cool northerly winds over Belize. The cold front crossed Belize during the early afternoon hours of Sunday.
The strong continental surface high over the eastern United States produced pleasant weather for Belize through Tuesday (5th).Weather conditions remained mostly cloudy for the following two days as a light N’ly to NW’ly flow prevailed. Weather charts identified another cold front stretching from Florida to Vera Cruz, Mexico on Thursday (7th).Skies turned cloudy to overcast on Friday (8th) morning. Showers and rain occurred over the sea and along the coast with a few embedded thunderstorms. The cold front became stationary from Florida to the Bay of Campeche during Friday. A surface trough which extended from northeast Honduras (13°N83°W) across Belize to the Yucatan Channel (18°N91°W) initiated considerable cyclonic curvature to the low level flow over the western Caribbean and Belize. The upper level flow was a diffluent northeasterly produced by an upper level high centred near Belize. The weather pattern remained relatively unchanged during the week end. As a result our weather continued with several extended periods of rain showers occurring mainly over southern and central Belize. Middlesex in the Stann Creek district recorded 60.6mm followed by Baldy Beacon with 55.1mm for Saturday. For Sunday Barton Creek recorded 95mm, followed by Punta Gorda town in the south with 56.4mm.
On Monday, the surface trough extended from the coast of Nicaragua to the coast of Belize. Most showers and rain occurred along coastal areas. Hershey in the foot hills of the Maya Mountains recorded 29.4mm.Tuesday’s weather was a mixture of cloudy skies and sunshine. The showers remained concentrated largely along coastal Belize. Savannah in southern Stann Creek district measured the highest rainfall-40.5mm.The midday surface analysis for Tuesday located a cold front over the northwest Gulf of Mexico. On Wednesday (13th) satellite imagery resolved a bank of showers and thunderstorms along the entire coastline. Later in the day the showers and thunderstorms occurred inland.Baldy Beacon recorded the most rainfall with 42.3mm, followed by Barton Creek with 37mm.Though the cloudy and rainy weather persisted on Thursday, Belize radar indicated the greater portion of the rainfall was offshore Belize. Surface analysis identified a dissipating frontal boundary from the Atlantic through the Florida Straits to the southeast and southwest Gulf of Mexico. Media reports of flooding started coming from the western and northern parts of the country. These reports included stories of bridges being washed away, flooded portions of major road arteries and Galen University having to cancel classes because of mud filled class rooms and library. Friday’s weather commenced in the much the same way as earlier in the week. Belize radar located showers, rain and isolated thunderstorms over and offshore northern Belize and coastal waters. The weekend’s weather shaped up much better as a light easterly surface flow prevailed. An upper level higher near the Yucatan Peninsula was producing an extensive canopy of dry air over the central Caribbean. As the center of the high translated slowly west, more dry air encroached over Belize.
The sunny weather continued at the start of the pen ultimate week in November. Much the same type of weather persisted for the following days in the week. During Friday morning (22nd) showers occurred with much more frequency as a moist northeasterly surface flow benefitted from the support an upper level high located near Belize. The rainy weather persisted during Friday evening. Saturday’s weather was cloudy with showers and thunderstorms occurring over northern districts, coastal areas and the south as well. However, the showers decreased noticeably Saturday evening. Cool temperatures prevailed on Sunday morning. Light showers later in the morning occurred mainly due to coastal convergence. A cold front appeared on weather charts over the northern Gulf of Mexico with the portion over the western Gulf of Mexico being stationary.
During Monday (25th) a portion of the cold front extended from the Atlantic Ocean to central Cuba where the front was stationary. A warm front extended from the stationary front to a surface low over the northwest Gulf of Mexico. A cold front also extended south to the Bay of Campeche from the frontal low over the western Gulf of Mexico. Showers and thunderstorms developed along southern and some coastal areas Tuesday afternoon as the front headed across the Yucatan Peninsula. Strong ridging which occurred over the western and southern Gulf of Mexico produced gusty surface winds during the showers which occurred in the afternoon and evening. The cold front crossed Belize Tuesday night. Wednesday’s weather was cloudy, windy and mostly dry. A strong high pressure ridge extended across the western Gulf of Mexico to southern Mexico, Belize and Central America during Thursday (28th).Most parts of the country experienced their coolest temperatures for the month on Thursday morning. The cool and mostly dry weather persisted on Friday (29th).Cloudy skies, punctuated by periods of light rain, characterized weather conditions for the final day in November. The cold front was at this time defined as a shear line extending from the Bahamas, central Cuba to the Bay Islands, Honduras.
