More rain today. measured 29 mm. Total for month now 12.9 inches. There will be a brief dry spell but then the large tropical wave shown in image is headed this way for later this week. The Saharan air layer has been shrinking recently so we may be in for a spell of wetter weather.

The latest tropical wave that passed through Belize on Sunday and Monday left behind about 4 inches 0f rain. This brings the total rainfall so far for July at 11.7 inches or almost 300 mm. This rainfall is fairly normal for this time of year. There has been no significant flooding since the rainfall has been well spread out over the period so there was not a lot of rain at one time. Another but weaker tropical wave is approaching which should reach here Thursday.

The Upper Low mentioned previously has disappeared overnight and the weather is calm this morning. Rianfall measured to be 12 mm most of it falling between 1900 and 2000 hr local time.

An Upper Level Low (see right) near Cancun Mx is setting off some stormy weather starting about 1800 hr.
At the moment we are getting mostly strong winds but only light rain. Will make a report in the morning.

The weather system shown in the previous report deteriorated overnight and did not produce the heavy rain indicated. However, it still managed to affect Belmopan as it passed up the coast of Belize. There were some showers overnight and then a period of wind and rain around 10 AM. Total rainfall from the system measured almost 25mm. The weather behind this tropical wave is hot and dry. The total rainfall so far for July is 118 mm or 4.6 inches.

The last in a series of tropical waves is approaching. This one appears to be the strongest in the series. Could bring some heavy rain tonight. Will update later today.

For the month of June 2012 I measured 247 mm or 9.7 in of rain, most of this at the beginning of the month and mid month. The last week of the month was more dry than normal. For my location I considered the rainfall below normal for June. The soil at the end of the month was hard and dry. I have not yet done any planting of seed due the fact that I have been predicting a dry spell since the area between the Caribbean and Africa was filled with dry, dusty Saharan air and it was moving towards Central America. Today the Caribbean is still extremely dry as shown in the water vapour image. There is a wave in the lower right that is approaching and may bring some showers by mid week.

Total rainfall so far this month 244 mm or 9.6 in The weather has now become considerably more dry. The region between here and Africa is extremely dry (see image). Not sure where the next rain will be coming from.

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.

The monsoon trough is now running up the west coast of Central America. Also a trough of low pressure has formed off the east coast. Last night an area of rain moved northward along the coast of Belize. A storm cell must have formed over Belmopan and I measured 66 mm (2.6") of rain this morning which was a surprise since I did not hear any heavy rain all night. Conditions in the Caribbean have changed dramatically over the past 36 hours. The dry air is rapidly being replaced with rain clouds.
