At 10 a.m., the National Hurricane Center upgraded Harvey to a tropical depression. A Tropical Storm Watch is now in effect from San Luis Pass to High Island. In addition, Hurricane Watch is in effect from Port Mansfield to High Island and a Storm Surge Watch from Port Mansfield to High Island.

Tropical Depression Harvey was centered near 21.5 N and 92.5 W or about 535 miles east-southeast of Port O’Connor. Sustained winds were 35 mph and central pressure 1006 MB (29.71 inches). Harvey was moving northwest at 9 mph with landfall expected along the central Texas coast.

Torrential and prolonged rains, elevated tides and possible storm surge and high winds to hurricane intensity will be possible near the landfall site as Harvey strengthens to a strong tropical storm or minimal hurricane. Another major problem is that Harvey may slow down as it nears the coast and even drift around the coastal plain and northwest Gulf, resulting in a long duration of wind, tides and torrential rains.

Needless to say, we all need to pay attention to local advisories as they appear and prepare for possible hurricane conditions. I will provide updates as the situation warrants.

Thanks for always being on top of these things, Mr. Blazyk.

In keeping with the subject, note to anyone deciding to buy a generator for hurricane season. Don't forget, it doesn't matter if you can power stuff more than your neighbor's generator with it, once you run out of gas and can't get more.
