A surface low pressure is situated just north of Belize and is drifting slowly northwestward. Moisture from the Pacific is being transported into this low pressure with the result that thundershowers are rotating across Belize moving from northwest to southeast. One of these thundershowers has recently occurred from 4:30PM to 5:30PM with rainfall of 1.43 inches. Meanwhile the eastern Caribbean is relatively dry. This dry air is having difficulty pushing into Central America. So far in May I have measured 142 mm or 5.6 inches of rain. The rainy season rain normally originates between here and Africa, however it is still dry in this region. The current rain is a local event.
