More Moisture Coming To Guatemala

It appears that the moist air mass mentioned in the previous post (#2 in the image) is becoming more active due to interactions with a ridge. This moist air was expected to bring rain for this weekend, mainly on Sunday, and now convective activity is increasing.

There's a small but non-zero probability that the mass could start rotating. If that happens then the system will throw moisture out over a much wider area and it could develop into a tropical storm, so it's something to keep an eye on because it's quite close and will likely bring significant rain this weekend.

The region marked #1 in the image started to get interesting early this morning because it has a good chance for development but it's far away and not a worry to Guatemala at this time.
