A tropical wave over the western portions of the Yucatan Peninsula will move slowly northwestward today and move back out over water. Currently the National Hurricane Center doesn’t have this system developing in the next 5 days. The wave should track to the northwest and will eventually pump deep tropical moisture into SETX Sunday through Tuesday. The rain chances should be higher toward the coast with the most intense rainfall focused mainly south of the Interstate 10 corridor. Widespread accumulations of 1 to 3 inches is likely through the course of the event but the focus should be on the intense rainfall rates Sunday PM-Monday evening. Isolated amounts in excess of 5 inches will be possible where storms train.
