At 5PM a little speck of a squall line dumped 19 mm on already wet Belmopan in 20 minutes. Total for month now almost 13 inches. Ground is saturated due to lack of hot sun and little wind for drying.

Actually the rain did not arrive until midday Sunday 21 Oct 2012. There was a heavy downpour around noon. Measured over 40 mm rain. There was no wind with the rain. Total so far this month ********* 11.9 inches.

The moisture mentioned previously has arrived. Light Showers began around sunrise and are now becoming more heavy. The heaviest rainfall should arrive tonight.

Belize is back to dry weather for the past three days. This dry should continue until this weekend 21 Oct. 2012 when some moisture builds up in the southwest Caribbean. Rainfall so far this month is 227mm.

There has been a lot of moisture around Belize over the past few days. Frequent showers occurred last night. At sunrise this morning I measured 41 mm. So far this month October 2012 rainfall is 7.9 inches. Seems to be making up for the lack of rain last month.

Belize is right now in a region of low and variable upper air steering currents and this is allowing for some isolated afternoon showers due to unstable moist conditions. The warm moist air is running up and over a weakening cold front in the Gulf of Mexico. This system should clear out by the weekend.

We appear to be under the influence of a classic OMEGA block. The moisture to the east has been transported to the north leaving Belize in dry but unstable air with very little upper air circulation. Have no idea how long this block is going continue. Solar activity has been very low recently with weak solar wind. Update: A small storm cell developed around Belmopan about 2PM and produced a heavy shower that lasted 1 hour. Measured a rainfall of 1.8 inches. The cell dissipated quickly thereafter.

There is a small Upper Level Low just off the coast of Belize which seems to be blocking the westward movement of the weather to the east of this cell. This is keeping the sky over Belize clear. Total rainfall for September was only 90mm which is much below normal. The soil moisture is abnormally low.
