<span-size:10.5pt;font-family:"Courier New";color:black">
<span-size:10.5pt;font-family:"Courier New";color:black">Harvey's eye has moved inland gradually during the past few hours,
<span-size:10.5pt;font-family:"Courier New";color:black">and maximum winds have decreased significantly since landfall.
<span-size:10.5pt;font-family:"Courier New";color:black">Radar velocity data from the Corpus Christi NOAA Doppler radar are
<span-size:10.5pt;font-family:"Courier New";color:black">showing winds as high as 90 kt at an elevation of 3000-3500 ft in
<span-size:10.5pt;font-family:"Courier New";color:black">the northwestern eyewall. The advisory intensity is therefore set
<span-size:10.5pt;font-family:"Courier New";color:black">at 85 kt, which could still be a little generous. Continued
<span-size:10.5pt;font-family:"Courier New";color:black">weakening is expected as Harvey's eye continues to move inland, and
<span-size:10.5pt;font-family:"Courier New";color:black">maximum sustained winds are likely to fall below hurricane force
<span-size:10.5pt;font-family:"Courier New";color:black">later today. A more gradual weakening trend is anticipated after
<span-size:10.5pt;font-family:"Courier New";color:black">that point, and Harvey is forecast to maintain tropical storm
<span-size:10.5pt;font-family:"Courier New";color:black">strength at least through day 4, especially if part of its
<span-size:10.5pt;font-family:"Courier New";color:black">circulation remains over water. The updated NHC intensity forecast
<span-size:10.5pt;font-family:"Courier New";color:black">continues a similar weakening trend noted in previous advisories and
<span-size:10.5pt;font-family:"Courier New";color:black">is closest to the HFIP Corrected Consensus Approach (HCCA).
<span-size:10.5pt;font-family:"Courier New";color:black">
<span-size:10.5pt;font-family:"Courier New";color:black">The initial motion has continued to decrease, and it is now
<span-size:10.5pt;font-family:"Courier New";color:black">estimated to be 325/5 kt. As the steering currents around Harvey
<span-size:10.5pt;font-family:"Courier New";color:black">continue to collapse, the cyclone is expected to stall or meander
<span-size:10.5pt;font-family:"Courier New";color:black">inland over southeastern Texas. Only a few models show any sort of
<span-size:10.5pt;font-family:"Courier New";color:black">definitive northeastward motion at the end of the forecast period,
<span-size:10.5pt;font-family:"Courier New";color:black">and for the most part, the most reliable models keep Harvey over
<span-size:10.5pt;font-family:"Courier New";color:black">southeastern Texas through day 5. The NHC track forecast depicts
<span-size:10.5pt;font-family:"Courier New";color:black">Harvey taking a slow counterclockwise loop just inland from the
<span-size:10.5pt;font-family:"Courier New";color:black">coast. This track is expected to exacerbate the potential for
<span-size:10.5pt;font-family:"Courier New";color:black">catastrophic flooding from heavy rainfall at least through the
<span-size:10.5pt;font-family:"Courier New";color:black">middle of next week.

<span-size:10.5pt;font-family:"Courier New";color:black">
<span-size:10.5pt;font-family:"Courier New";color:black">1. Harvey is moving farther inland over southeastern Texas and
<span-size:10.5pt;font-family:"Courier New";color:black">continues to bring life-threatening storm surge, rainfall, and wind
<span-size:10.5pt;font-family:"Courier New";color:black">hazards to portions of the Texas coast.
<span-size:10.5pt;font-family:"Courier New";color:black">
<span-size:10.5pt;font-family:"Courier New";color:black">2. A Storm Surge Warning is in effect for much of the Texas coast.
<span-size:10.5pt;font-family:"Courier New";color:black">Life-threatening storm surge flooding could still reach heights of 6
<span-size:10.5pt;font-family:"Courier New";color:black">to 12 feet above ground level at the coast between Port Aransas and
<span-size:10.5pt;font-family:"Courier New";color:black">Port O'Connor. For a depiction of areas at risk, see the Storm
<span-size:10.5pt;font-family:"Courier New";color:black">Surge Watch/Warning Graphic at hurricanes.gov. Due to the slow
<span-size:10.5pt;font-family:"Courier New";color:black">motion of Harvey and a prolonged period of onshore flow, water
<span-size:10.5pt;font-family:"Courier New";color:black">levels will remain elevated for several days.
<span-size:10.5pt;font-family:"Courier New";color:black">
<span-size:10.5pt;font-family:"Courier New";color:black">3. Catastrophic and life-threatening flooding is expected across the
<span-size:10.5pt;font-family:"Courier New";color:black">middle and upper Texas coast from heavy rainfall of 15 to 30 inches,
<span-size:10.5pt;font-family:"Courier New";color:black">with isolated amounts as high as 40 inches, through Wednesday.
<span-size:10.5pt;font-family:"Courier New";color:black">Please refer to products from your local National Weather Service
<span-size:10.5pt;font-family:"Courier New";color:black">office and the NOAA Weather Prediction Center for more information
