On Ambergris Caye this morning it looks like a repeat of yesterday. Sunny and very windy (21 mph.) with the sea so choppy boats should stay tied to the docks. Our expected high is 90.

From Belmopan...

Hot humid air continues as the Caribbean easterly continued most of the night, but the orange smoke dust is less. The radar packed up yet again, but I don't expect any rain around. The ITCZ is becoming very active down around Panama. The Pacific high level more southerly near us, due to the ITCZ activity further south, keeping our air warm and very humid. That cold front not having any effect on our weather.

Looks like today will continue like yesterday, hot and humid, no rain.

Temperatures in Belmopan :
( Coast usually cooler, hills even cooler ) Sat max. 32°C 89°F Last night min. 26°C 78°F

Monthly Weather Summary, April 2017

National Meteorological Service of Belize

April 2017 began typical with hot, hazy and dry weather as an East-Southeast airflow prevailed over the country from the 1st to the 5th. Only isolated thunderstoms developed mainly over the Maya Mountains and near the western border during the first few days of the month. As is customary in April the Atlantic High Pressure ridge dominated the region and heat lows developed over Mexico producing a tight pressure gradient resulting in gusty winds. By the 6th a light to moderate East-northeasterly flow developed due to high pressure ridges northwest and northeast of the country. On the 7th a cold front was over the Yucatan Peninsula which supported the east-northeast flow and a few showers over northern and western Belize. The east-northeast surface flow persisted on the 8th and isolated showers affected central and southern coastal areas during the morning then conditions returned to hot and dry by afternoon. Mainly fair and warm conditions continued on the 9th and 10th with isolated showers over northern areas on the 9th and over the south on the 10th.

A light to moderate east-northeast surface flow prevailed from the 11th to the 15th as the Atlantic Ridge extended into the Gulf of Mexico and a weak low pressure was north of Puerto Rico with troughing extended into the northeast Caribbean. On the 11th a few showers affected central portions of the country and offshore Dangriga in the afternoon. Moisture was high over the south on the 12th and a few showers developed south and over the Maya Mountains. On the 13th morning scattered showers were observed across the country then conditions became generally fair with a few showers mostly over central and southern areas. An increase in low level moisture on the 14th resulted in a few showers over the sea and in the north. On the 15th morning a few showers developed south then moved over central areas in the afternoon. Middlesex recorded 17.2mm of rainfall. By the 16th a slack pressure gradient was established between a broad ridge over the northwest Caribbean and a surface trough over the south central Caribbean resulting in a light easterly airflow.

The 17th started with a light to moderate easterly flow and a few morning showers across the country then by afternoon skies became increasingly cloudy as numerous thunderstorms developed over central and northern areas. At the PGIA intense thunderstorms and severe lightning were observed along with moderate to heavy showers. An upper level trough was over the Gulf of Mexico which produced a divergent pattern over the area. The evening sounding showed a moist and unstable atmosphere with precipitable water value 44.86 and K index of 29.9. The 18th to the 20th a few showers and isolated thunderstorms continued to affect mostly coastal and southern parts of the country in the morning and the Maya Mountains in the afternoon due to daytime heating. On the 18th San Pedro recorded 36.1mm of rainfall while Dangriga received 25.3mm. The 19th saw a decrease in showers in the evening but during the night showers, light rain, isolated thunderstorms and gusty winds affected northern and coastal areas as an upper level low over the Bay of Campeche shifted eastward and a diffluent pattern was over northern Belize. Showers continued on the 20th with Belmopan recording rainfall of 55.6mm, Belize City 44.5mm and PGIA 36.8mm. By evening moisture and instability decreased, and Tropical Storm Arlene, the first tropical storm of the Atlantic hurricane season formed over the Atlantic.

The 21st was mostly fair and dry as a slack pressure gradient over the area kept winds light. Tropical Storm Arlene remained over open waters and was eventually absorbed by an extra-tropical low pressure system losing its tropical characteristics. On the 22nd a light east-southeast airflow prevailed producing fairly warm conditions. Isolated thunderstorms developed inland due to intense daytime heating and moved over Biscayne Village producing a freak storm or tornadic type phenomenon. Local reports suggest about eight homes were damaged. On the 23rd winds were light and from the north-northwest due to ridging west and northwest of the country. As a result temperatures were relatively mild. The 24th started with a north-northwest flow but during the daytime winds shifted to the southeast as thermal troughs developed over Mexico.

The last week of the month seasonably warm, hazy and dry conditions resumed over the country as the Atlantic High Pressure ridge dominated. On the 25th weak ridging over the northwest Caribbean and a broad trough over the western Gulf of Mexico with axis along eastern Mexico maintained a light east-southeast airflow. A cold front dissipated over the extreme northwest Caribbean and northern Yucatan. From the 26th to the 27th thermal troughs over Mexico and the Atlantic ridge supported a moderate east-southeast airflow that became strong and gusty from the 28th to the 30th as the pressure gradient tightened. These strong winds produced rough sea conditions and as a result small craft warnings were issued.
