Weather Underground Forecast for Thursday, June 20, 2013.

Heavy rains and gusty winds are expected to continue for southern Mexico as Tropical Depression Two continues westward across the extreme southern tier of the Bay of Campeche through Thursday morning. No significant strength change is forecast for this storm before it makes landfall near Veracruz by Thursday. Regardless of the exact track of the center the primary concern continues to be heavy rainfall, which could cause significant flooding over portions of Central America

and eastern Mexico. The depression is expected to produce total rainfall accumulations of 3 to 5 inches with maximum amounts of 10 inches across portions of the Yucatan Peninsula and southern Mexico. These rains could cause life threatening flash flooding and mudslides, especially in mountainous areas.

Meanwhile, a tropical wave in the eastern Caribbean Sea will continue westward into the central Caribbean basin on Thursday. Light to moderate showers, chances of thunderstorms and locally heavy rain are expected for Hispaniola, Jamaica, and eastern Cuba with the passing of this wave.

Elsewhere, expect continued widely scattered light to moderate showers and thunderstorms in the southwestern corner of the Caribbean basin and from Panama through Nicaragua due to the proximity of the monsoon trough.

In South America, warm and humid conditions will support more shower and thunderstorm activity in the northwestern and northern tier of the continent. To the south, high pressure strengthens over northern Argentina and Uruguay with dry and calm conditions. Return flow associated with this system will pool along the tail of a frontal disturbance extending into southeastern Brazil leading to light to moderate showers with periods of locally heavy rain and chances of thunderstorms in Santa Catarina and Parana. Further south, heavy precipitation will persist across southern Chile as moist onshore flow and low pressure prevail across the region.
