Regional weather: Monday, June 27 - Extreme southern Mexico: Persistent tropical convection is predicted to cover the Yucatan and Southern Mexico regions due to upper-level divergence in the atmosphere and the interaction with approaching tropical waves.

Trajectory weather: Mixed cloud cover with rain and thunderstorms possible later in the afternoon. High of 35Cand a low of 24C.

Trajectory confidence: High

OUTLOOK: ***Moderate Threat***

Monday and Tuesday: The constant threat of clouds, rain, and thunderstorms creates a persistent and favorable environment for disease development. However, the strength of the source is suspect and there is a good chance for the sun to peak through the clouds for brief periods. Moderate risk near the source area. Low Risk otherwise.
