A e tropical wave appears to have moved off the coast of Africa. As it organizes into a storm it would be named Lee. That means there are currently 4 tropical disturbances in the Atlantic, seen below.

From Belmopan...

Well H IRMA is blowing itself apart, it was too tight, too compact, too powerful, it has dropped from Cat.5 to Cat.3 over night, somewhere I saw the weather people say that theoretically a hurricane could not sustain 185 mph winds, well looks as if they were right, although it has now run into the weather front that has been coming across the USA, I think hitting Cuba has also had a part in its breakup. But even Cat.3 is a dangerous hurricane and the sea has already been churned up when it was Cat.5

As part of its breakup, its high level clouds have been thrown way out and now filling the western Caribbean and even coming over Belize. Another strange effect is that the present white clouds over central Belize are coming from the WEST and not from the Caribbean, Ah, finally got the NASA web site to work, all low level clouds over Belize are moving from the West, high level from Irma coming in from the East, but not conflicting with the low level clouds, except out at sea.

Looks like today will be largely sunny, but with white clouds from the West, no indication of rain on land yet.

Now you can see the larger picture, the weather front across the USA, which is blocking Irma, causing it to change direction and why KATIA was going to go up northwards into the USA. You can also see how H IRMA has spread out, filling the west Caribbean area and even sending clouds over Belize.

Temperatures in Belmopan :
( Coast usually cooler, hills even cooler ) Fri max. 32°C 89°F Last night min. 26°C 76°F

The H IRMA has pulled its self together and reforming, but presently, only as a Cat.3.

Its high level cloud blow out, has now covered all the western Caribbean and part of the Gulf. Although its centre is reforming, it has not yet started to turn northwards. What can't easily be seen is that although its outpouring in in a clockwise rotation, the lower rotation, from surface up to several thousand feet, as normal in the northern hemisphere, in anti-clockwise and is sucking low level air in from the Yucatan and Belize, resulting in the white clouds over Belize coming from the WNW. Meanwhile H JOSE has just missed Barbuda and going north away from the Caribbean islands.

Compare this to my earlier pictures.

From Belmopan....

H IRMA still has not started to turn northwards. It has been running along the north coast of Cuba. Some Weather people have been saying Irma is now moving away from Cuba, but that is misleading, the reason is Irma is still running a more or less straight line, but the Cuba coastline curves downwards where Irma has gotten to.
