At about 11Z today, Katrina made landfall on the Mississippi River delta in southeast LA as a potent CAT4 hurricane. Maximum sustained winds were estimated to be 120kts with a MSLP of 920mb. Then it proceded north... the western eyewall hitting New Orleans, and the eastern eyewall hitting Gulfport and Biloxi. There are already reports of significant flooding and damage all along the coast in LA, MS, and AL -- from New Orleans to Pensacola. It's still too early to get a complete picture of what has transpired this morning, but it will be an extremely costly disaster. Cities as far east as Mobile, AL had levees topped and flood waters racing into the city. Buoys just offshore reported waves of 40+ ft ahead of the storm. The storm has since moved inland and weakened to a CAT1 hurricane as of this writing. Further weakening will occur, but now the primary threat is from inland flooding, and that is a risk for the next several days in the southeast and Ohio Valley.

Remember that tornadoes and flash floods are big dangers from hurricanes that have made landfall... even quite far from where it made landfall. As of 19Z, Hurricane Katrina was located at 31.4N 89.6W (near Hattiesburg, MS) and tracking N at 15kts. The intensity is 80kts and the MSLP is 955mb. On its forecast track, it will be passing over TN, KY, and OH over the next couple of days. If you wish to help the Katrina victims, the American Red Cross has a donation form at https://www.redcross.org/donate/donation-form.asp Due to excessive shear in the critical formative stage, TD13 has dissipated into an open wave and is no longer forecast to intensify. It will be watched for signs of regeneration though. However, a relatively new wave has exited the African coast and is located near 10N 32W, just southwest of the Cape Verde Islands. It shows signs of development and conditions should be favorable for gradual organization.Please visit my tropical Atlantic headquarters.
