Almanac

Some patchy fog is possible early this morning. Otherwise, very warm and humid conditions are expected today with high temperatures in the low to mid 90s at most locations. Isolated showers and thunderstorms are possible by late afternoon. Favorable marine conditions can be expected today with seas of 2 to 4 feet and southeast winds of 10 to 15 knots.

Minor coastal flooding will be likely along the lower Texas coast tonight as water levels are expected to rise to 1 to 2 feet above Mean Higher High Water (MHHW ) at high tide late tonight. Vehicles driving along narrow beaches will experience problems with the higher water levels along the beach.

An upper-level disturbance combined with the remnant moisture from eastern Pacific tropical storm Octave will cross the Lower RGV late tonight in the pre-dawn hours Monday. Thunderstorm clusters or bands are expected to leave more than an inch in southern Cameron County, but locally heavier cells could produce 3 or more inches of rainfall in a short period of time. Late night/early Monday morning drivers should be aware of torrential rainfall with low visibility as well as flooding in poor drainage locations.

There is a moderate risk of rip currents today at the area beaches due to persistent swell. High temperatures will be in the mid to upper 80s under partly cloudy skies. Isolated showers and/or thunderstorms may be possible today. If caught in a rip current, don't fight the current, swim even with the shore, until current weakens, then swim to shore.

Opportunities for showers and thunderstorms will be expected through this week with the arrival of a pair of cold fronts. The first front will be the weaker of the two but should result in refreshing morning temperatures. The second cold front is expected to bring even more of a cool down on Friday.
