The image shows the weather at 2315 hr May 30. Around 10PM last night, thunderstorms developed along the southern Guatemala border and moved to the northeast across Belize. Belmopan experience some heavy thunder around 11 PM. By midnight the storm had passed. Rainfall was measured to be 35mm or about 1.4 inches. This brings the total rainfall for May to 276 mm or 10.9 inches which is above normal. All of this rain fell in the last half of the month. Virtually all of the rainfall was due to moist air flowing north to northeastward across Central America from the South and Pacific. The central Caribbean itself was and still is relatively dry. High Pressure in the eastern Caribbean created an anticyclone circulation which carried moisture along the north coast of South America then up through Central America. There is a body of African Dust over the Atlantic between here and the west coast of Africa.

Today was sunny and warm. Yesterday rainfall was 0.8 in or 22mm. A weak tropical wave is approaching which may produce some rain tomorrow night. Once this wave passes we should be under the influence of the dry African air. I have not yet planted any seed in my garden in anticipation of the return of dry air. The dry should last till mid June.

An upper level trough of low pressure extends from tropical storm Beryl off the east coast of Florida down to Honduras near Belize. An area of thundershowers formed overnight along this trough northeast of Belize and moved southward down the coast of Belize. A thundershower began about 4 AM which turned into continuous rain from 5 AM to around 9 AM. East of Belize the Caribbean is still dry. Most of the rainfall lately is concentrated over Central America. Circulation on the Pacific side of Central America is throwing a lot of moisture to the northeast over Belize.

There was a shower sometime between 3 and 4 AM which produced 0.26 in or 6.6 mm rainfall. The band of showers moved across Belize from west to east. The Atlantic continues to remain relatively dry compared to the Pacific side. Therefore, it is my opinion that the real Caribbean rainy season is not yet underway.

There were more showers last night bringing the total for May so far to 7.2 inches. The band of moisture that has been affecting the region for the past 9 days has now drifted off to the east. We are now finally back to dry weather again. The weather should now remain relatively dry until we start encountering the Atlantic hurricane season which begins 1 June 2012. I am predicting a fairly quiet season for hurricanes at least until October.

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.

The rainfall from the weather system mentioned in my previous report produced almost 70mm or 2.7 inches of rain over May 15-16. Today May 17 the weather is dry again and cooler than before, much more comfortable. The solar activity has decreased over the past few days. The large sunspot has decayed. The forecast is for thunderstorms to develop tomorrow, but will see what happens.

The area of moisture is rapidly increasing. The wind shear pattern on the Pacific side of Central America is beginning to shift from the dry to the rainy season. The sun is active with a strong solar wind of 567 this morning. There was a trace of rain before sunrise this morning. Some change in the weather should be happening soon.

The massive sunspot has rotated towards the centre of the sun and is crackling with flares. Storm activity is increasing on the Pacific side of Central America. An area of moisture east of Central America is now increasing. Something may be developing for the weekend.

The large sunspot is now visible. In the past few days the active weather that was moving north has disintegrated and the chance of rain for this coming week has now greatly diminished.

The tropical rain zone or ITCZ is slowly moving northward now as shown in the image. A new group of large sunspots is just beginning to emerge on the sun. The full moon starts tonight 5-6 May and is closest to Earth for the year, making it look 14% bigger. All this should combine to set off some active weather here sometime between May 8 and May 13. Will have a clearer picture of this in a few days.

Its May 1 mayday and a holiday here. Sky is clear and about 33C. No sign of rain at this time. Same weather day after day.
