Some thundershowers in Belmopan last night. Measured 9 mm of rain. Total rainfall so far for June is 8.6 inches or 217 mm. Cause of the unstable weather is the proximity of the Monsoon trough of low pressure. The low pressure is actually at surface. There is currently an upper high over the area with a clockwise circulation so that the high cloud is moving in from the NE rather than from the west. Meanwhile the eastern Caribbean continues to be under the influence of dry air from Africa.
