Tropical wave heads into Bay of Campeche

ATLANTIC

* A tropical wave moving west-northwestward into the Bay of Campeche is bringing disorganized but locally heavy showers and thunderstorms to the Yucatan Peninsula, southeast Mexico, and parts of Central America.

* This system could organize some on Tuesday or Wednesday as it moves through the Bay of Campeche and the shearing winds aloft relax, but may only at best become a tropical depression.

* Any developing tropical low and associated heavy rainfall will quickly move into northeast Mexico midweek and beyond.

* Southernmost Texas could see an increase in shower and thunderstorm activity.
