Tropical Depression Two

Monday’s Outlook

Extended Outlook

Radar Outage

Tropical Depression Two is currently drifting north-northwestward in the eastern Gulf, and is expected to become a tropical storm in the northeastern Gulf by tomorrow or Tuesday. A westward motion is expected by Wednesday, bringing the system towards SE Texas by Thursday-Friday. Highly uncertain track / intensity forecast beyond Wednesday. Hurricane Hunter reconnaissance aircraft flew into this system earlier today and aided in determining the current central pressure and maximum sustained winds. Tropical Storm force winds could arrive in our coastal waters as early as Wednesday night with increasing chances for rain and thunderstorms Thursday-Friday across SE Texas. Confidence on expected impacts and timing will increase over the next couple of days as additional data become available.

Partly cloudy skies are expected with highs in the mid to upper 90s. Heat index values of 100-105 are expected. Lows will settle in the low to mid 70s.

Heat will continue into at least midweek with rain chances increasing shortly after midweek.

HGX radar is currently out of service due to an unanticipated disruption. Electronic Technicians have been notified.
