Bands of Weather – Category 1 Harvey Moves Through


These are the outer bands that are actually creating the most substantial rainfall at this time and, it’s impacting central Texas. This is extending all the way back down towards the Houston area. If you remember over the last several days, the highest rainfall totals were going to clip south central Texas including our Austin metro counties. It is digging into the Gulf of Mexico and pulling up so much gulf moisture and throwing it over the large swath of area and this is what was anticipated.

There is so substantial and so drastically different from one edge of the area to the other. Here is Hurricane Harvey it is still technically a category 1 storm. I want to update you. Max sustained wind speeds are 80 miles an hour. Once they fall to 73, we are officially dealing with a tropical storm that is anticipating happening later today and more. So tonight the way the storm is weakening, it’s losing a lot of the fuel source, losing the Gulf of Mexico moisture to be more specific.

So that is a very good chance that we could be dealing with the tropical storm status much sooner than anticipated. It is getting a little interesting not only because we have periods of heavy rainfall Fayette county, you had two to three inches within two hours earlier this morning there have been a few pockets where we have had the broad rotation and that’s created a radar indicated tire rotation.

Nothing ever reaching part of the ground that was a bit of a concern in western lee county earlier as of right now, heaviest rainfall is actually embedded within the widespread steady moderate to light showers and heavier pockets along 130, it is pouring in east Austin as it continues to make its way from east to west heading towards downtown, 20 to 25 miles per hour as moisture has been moving so good news, heavy rainfall isn’t just sitting in east Austin. It is getting in and getting out the problem is we are going to have more moisture kind of piling on top of that behind it.

National weather service is concerned because it was being indicated in Hays County, the area of broad rotation just west but I’ve been checking our velocity maps look at this, not only has the heavy rain fallen apart but our wind map showing how we are struggling to get any type of rotation together. That is good news, no tornado warning in that area.

This is something that we’ve had to watch out for because the showers and storms have the potential to quickly develop or at least spin up a brief tornado, all things tropical moisture that’s why Fayette and Lee County are under a tornado because you are not under a tornado. This storm is about 80 miles per hour max sustained wind speeds are at 80 miles per hour if it drops seven miles per hour within the next couple of hours, that’s it we finally have a tropical storm status.

Heading along the gulf coast where it made landfall and maybe go up more, so towards east central Texas by the middle to the beginning of your upcoming work week. So this just shows you how that cone of uncertainty turns into a massive bubble but this storm will likely sit, it will downgrade quickly but have the potential to dig up gulf moisture and allow it to continue to rain here over, and east of our metro counties, that’s where we are the most substantial rainfall is forecasted to fall especially over Fayette County.

That potential to be there an hour to hour that moisture continues to spin from east to west over the next several days that are why really our eastern counties could see isolated tornadoes of 15, maybe 20 inches or more. Whereas metro, maybe about 7 to 10 inches.
