Extreme Heat and Dry warning. The TPW has dropped well below the 10 degree latitude north. The region between Africa and South America has very low moisture. This dry air should reach Belize by the middle of this coming week. This is also the time of the New Moon. The sun is almost totally free of sunspots.

There has been an increase in moisture overnight with a trace of rain from low clouds just before sunrise. The water vapour (TPW) pattern in the Caribbean is beginning to look more complex with some moisture streaming north of 10 degrees latitude. The solar wind this morning was 486 kms which is fairly high considering the lack of any large coronal hole. Plus it is now 6 days after the full moon which is normally a time of potential rainfall. This increase in moisture may just be temporary and the dry weather should continue at least until a week after the next New Moon.

There is a wind shift line straight through the length of Belize. However there is no significant weather associated with this system except for an increase in the cloud cover and a strengthening in the breeze from the north. The air above Belize is still too dry and stable to produce any significant rainfall. The main band of TPW (water vapour) still lies just south of 10 deg latitude and is becoming more active on the Pacific side than on the Atlantic.

Very unusual to see a Cold Front invade Central America all the way almost to Nicaragua this time of year. The wind off the southern coast of Mexico very strong at 75 kph. Only light wind at my location in Belmopan Belize. There was no rain in Belmopan due to the passage of the Cold Front. The chance of rainfall in Belize should start increasing after the Full Moon on April 15. Also a new large Coronal Hole is opening up on the sun which will result in an increase in the solar wind staring the middle of next week.

A late season Cold Front wandered across Belize today with the main northerly force of the front arriving at 1754 hour with a strong gust of wind that blew leaves off the trees and kicked up some dust. The Upper Air is quite dry and stable so there is not much chance of any significant rainfall. There is a strong SW wind shear just west of the Belize/Guatemala border which is tearing the tops off of any developing rain cells. The effect of the front should only last until the end of the week and bring some relief to the heat.
