Three Weather Systems of Interest

There are three weather systems affecting Guatemala right now. Tropical Storm Erick and the remnant low of Dalila are over the Pacific off the west coast of Mexico. The third system is a large region of thunderstorms located over the Northern Yucatan and Gulf of Mexico. The system over the Yucatan has persisted for several days while gradually drifting west. At the present time, this third system is not expected to develop further.

All three of these systems are lofting lots of warm moist air into the upper atmosphere, some of which is causing rain over Guatemala and Southern Mexico. A lot of this warm, moist outflow is traveling northeast across the southeastern states of the United States where it is causing rains and flooding.
