Monthly Rainfall Summary for April 2016
Rainfall summaries are prepared by the Climate Section of the National Meteorological Service of Belize. The meteorological service maintains a network of over 25 rainfall stations that are situated across the country mainly in agriculture area. Rainfall is read at 9:00am each morning and this represents the rainfall for the previous 24hours.
Climatologically, the Atlantic High Pressure ridge usually dominates the region during the month of April. Its orientation typically produces a dry southeasterly airflow across the country. At times heat-lows may develop across southern Mexico which causes pressure gradients to tighten over the area resulting in gusty winds. However, when the centres of these systems are over or very near the country, pressure gradients would instead slacken causing light winds and an excessively high heat-index. This overall synoptic pattern for the month normally corresponds with dry and warm weather. The only relief would come in the form of an occasional cold front. On average about two cold fronts would cross the country during the month. These may be accompanied by strong to severe thunderstorms and they are the main producers of the little rainfall for the month. April 2016 was characteristically warm but much drier than normal. This is likely due to the fact that only one weak frontal boundary affected the country. The frontal boundary that affected the country on the 4th thru to the 5th was the main rainfall producer in the month of April. The rainfall received over most of the country resulted in most stations receiving rainfall way below their normal. Only two stations received rainfall above their normal, Tower hill over northern inland areas and Baldy Beacon in the higher elevation of the Maya Mountains as indicated in the graph below.
The next rainfall summary will be out in the first week of June 2016
