Heavy Rain Coming, Thursday, Friday (Update)

The leading edge of the heavy portion of the moist air mass discussed in the previous post is now arriving in eastern Izabal.

This is the tropics so there are no guarantees but I would prepare for heavy rain tonight (Thursday), all day Friday, possible extreme amounts of rain Friday night, and tapering off some time on Saturday.

Heavy Rain Coming, Thursday, Friday

There's a mass of heavily moisture laden air that is barely starting to arrive tonight (Wednesday night) and will start to make its presence known later tomorrow (Thursday).

I expect heavy rain Thursday night, and Friday day, and possible extreme amounts of rain on Friday night here in the Rio Dulce area.  Extreme would be 7 or 8 inches in one night.

Below is the current water vapor image.  (Those are not clouds.  It's a graphic depicting water content.)

Possible Late Season Cyclone Forming

The system circled in the graphic below has been developing slowly for the past few days.  During the past few hours its activity has become much more organized and at the moment it is developing rather rapidly.  Those of us in eastern Guatemala should keep an eye on this one.
