Rain in Our Future

Two tropical waves are affecting us here in Eastern Guatemala right now. One just passed us and another is over eastern Honduras and approaching at 15 kts. Both waves have air masses associated with them that are loaded with maximum moisture. So expect intermittent rain and possible thunderstorms over the next few days.

The forecast for Eastern Guatemala indicates a moderate amount of rain (about 10mm) each day for the next several days, although heavy downpours are always possible because the air is so unstable.

Out over the Leeward Islands is an area to keep an eye on. Shown circled in the image below is a large area of disorganized thunderstorms that is showing rotation and circulation. There are no significant features around that system that would inhibit outflow so it's probably going to develop.
