ROUGH WEATHER IN TEXAS, OKLAHOMA AND KANSAS AS A RESULT OF A TROPICAL STORM
As hard to believe as it may be, tropical storm conditions have been felt deep inland over Texas in such locations as Austin, San Antonio and other rural areas. Why? The remnants of TS Hermine are moving through and are only slowly weakening. The reason is more than likely due to the fact the conditions in the atmosphere were so primed and favorable that the storm did not get to reach its full potential over water- it ran out of time. So, instead of simply dying away quickly, it still tried to maintain strength even while over the Texas landscape. Several inches of rain has fallen casuing road closures and numerous problems throughout the eastern half of the Lone Star State. The same conditions, though perhaps a little less organized, will move in to southern Oklahoma and Kansas over the next couple of days. Along with the extreme rainfall rates, there is also the threat of severe weather as the circulation of Hermine encounters dry air from the land and the heating of the day. Isololated tornadoes are possible and people need to be aware of rapidly changing weather across the region.
Elsewhere, we now have 91L way out in the eastern Atlantic. This is the system that almost all of the major computer models are developing in to "Igor" over the coming days. Early indications are that it will track basically due west, perhaps just south of west, under a building area of high pressure across the eastern Atlantic. It poses no threat to land areas, except perhaps for the Cape Verde Islands. We'll have plenty of time to monitor the progress of this developing system. The rest of the tropics are nice and quiet- even ex-Gaston is now pretty much a non-issue. I'll have a morning update online by 9am ET.

HERMINE CONTINUES TO BRING HEAVY RAINS AND STRONG WINDS TO TEXAS
A quick-developing Hermine is still packing quite a punch over south Texas this morning. Heavy rains continue across a good deal of the eastern part of the state north of Corpus Christi. The center is clearly visible on radar near Alice, TX and is moving on a course for San Antonio later today. Make no mistake, the torrential rains from this system will be big news across Texas and perhaps even Oklahoma. Hermine is expected to track northward in to Oklahoma as what is called a post-tropical depression or low, meaning it is no longer a true tropical cyclone but still retains its low pressure and precipitation field. While this event will do much to restore water levels across Texas, this much rain this quick will cause significant flooding issues across the region. Be mindful of the situation and plan accordingly.
In the rest of the tropics, things are at a temporary lull as we await the next impulse of energy to fully emerge in to the eastern Atlantic from Africa. Computer models are almost in 100% agreement that we'll see "Igor" form from a complex of thunderstorms off the Cape Verde Islands towards the weekend. In fact, the pattern looks ripe for another round of several named storms coming up. The good news is that I see nothing that will affect land which is fine considering what Texans are dealing with.
Tonight on HurricaneTrack News/Talk, we'll take a look back at Earl, including photos and data that we collected on the NC Outer Banks. We'll also discuss the upcoming peak of the season and what we expect will be a very busy September ahead. It all begins at 9pm ET right on the homepage. I'll post another update this evening before the program.
