Hurricane Harvey Update 4:45 PM on Tuesday

Post by dan_s »

The sun is out in Sugar Land, Texas!!!!!!!!!!!!!!!!

It is still raining, but nice to see some sunshine. Rain here is expected to end tonight.

Tropical Storm Harvey has set a preliminary Lower 48 U.S. rainfall record for any tropical storm or hurricane as it continues to soak the upper Texas coast and Louisiana, worsening record-breaking, catastrophic flooding.

The Cedar Bayou gauge near Highlands, Texas has reported a preliminary 51.88 inches through 3 p.m. CDT Tuesday.

A Harris County Flood Warning System rain gauge near Friendswood, Texas, reported a four-day storm total of 49.32 inches through 9 a.m. CDT Tuesday.

If either of these are confirmed, it would be the heaviest storm total rainfall from any tropical cyclone in the continental U.S. in records dating to 1950, topping the 48-inch storm total in Medina, Texas, from Tropical Storm Amelia in 1978, according research by NOAA/WPC meteorologist, David Roth.

Suffice to say, this is one of the worst flood disasters in U.S. history, with record-smashing river flooding lasting well into next week.

The average rainfall within the Harris County Emergency Management network has exceeded that of Tropical Storm Allison (2001) in almost half of the time (2 to 3 days versus 5 days).

Allison was not even close to the damage this storm has caused and still causing. The clean-up for Allison cost over $10 Billion.

Still a named storm over 72 hours after landfall, Harvey is the longest a Texas landfalling hurricane has remained a named storm after landfall on record, according to Colorado State University tropical scientist Dr. Phil Klotzbach.

Harvey made landfall Friday night near Rockport, Texas, north of Corpus Christi, as the first Category 4 hurricane to landfall in the U.S. since Charley in August 2004. Rockport is almost totally destroyed.

Harvey's center is currently in the far northern Gulf of Mexico accelerating toward the north-northeast. On this track, Harvey's center will make a third and final landfall along the southwestern Louisiana coast late Tuesday or early Wednesday. Here's our latest forecast.

Still Days of Heavy Rain Ahead

The heaviest rain is now targeting areas near the upper Texas coast generally east of Houston, and parts of Louisiana. Beaumont, Texas, picked up 1 inch of rain in just 26 minutes early Tuesday morning, and is now in a flash flood emergency along with nearby Port Arthur.

Harvey's center of circulation is now just offshore, triggering tropical storm warnings from Port O'Connor, Texas, to Morgan City, Louisiana. A tropical storm watch is in effect from east of Morgan City, Louisiana, to Grand Isle, Louisiana.

The tropical storm had been stuck between two areas of high pressure and, but will finally make a concerted move northeast later in the week, as high pressure over the western U.S. finally weakens and Harvey is steered by high pressure centered near the Bahamas and Florida.

The National Hurricane Center is not expecting a significant strengthening of Harvey while it's briefly off the Gulf Coast, so the main concern should remain additional heavy rainfall.
