At 5 pm, Nate have winds at 90 mph, gusts up to 115 mph. Nate remains a category 1 hurricane and as I said in the beginning, it is running out of time to strengthen as it approaches the central Gulf coast. Shear may also having impacts on Nate. While there is still a chance for Nate to reach category 2 strength it is likely to remain a strong category 1 at landfall. Nate is currently only 50 miles south of the mouth of the Mississippi River and 140 miles south of Biloxi, MS. On the forecast track, Nate will move near or over the mouth of the Mississippi River in the next couple of hours and will make landfall somewhere along the Louisiana or Mississippi Gulf coast later this evening or late tonight.
The latest look at the radar, you can see the eye of Nate to the south of the mouth of the Mississippi River and moving to the north-northwest. Rainbands continuing to rotate onshore and each rainband will produce higher and higher winds. Tropical storm force winds will spread over the Louisiana and Mississippi Gulf coasts within the next hour or two, with hurricane force winds moving over the mouth of the Mississippi River within the next two hours, the Louisiana Gulf coast within the next 3 to 4 hours, and the Mississippi Gulf coast within the same time frame.
Impacts for the New Orleans metro area and the rest of the northeast Louisiana Gulf coast, as New Orleans and the Louisiana Gulf coast will likely be on the west side of Nate, winds will likely be on the order of 45 to 65 mph, with gusts to near or over hurricane force. Rainfall totals of 3 to 6 inches, with isolated amounts of up to 10 inches will be possible. Storm surge flooding will be the following…Grand Isle, Louisiana to the mouth of the Mississippi River…2 to 4 ft, Mouth of the Mississippi River to the Mississippi/Alabama border…7 to 11 ft. Isolated tornadoes may be possible.
Impacts for the Mississippi and Alabama Gulf coast, winds will likely be on the order of 75 to 90 mph, with gusts 100 to 110 mph, especially near and just to the east of where Nate makes landfall. Rainfall totals of 3 to 6 inches, with isolated amounts of up to 10 inches possible. Storm surge flooding is the following…Mouth of the Mississippi River to the Mississippi/Alabama border…7 to 11 ft. Mississippi/Alabama border to the Alabama/Florida border, including Mobile Bay…6 to 9 ft. A few tornadoes will be possible especially near and to the east of where Nate makes landfall. There was a least one reported tornado in Gulf Shores.
There will be other impacts as Nate continues to move inland. It will quickly weaken and will likely dissipate within four days or sooner. Rainfall amounts form the southeast, to the Tennessee and Ohio Valleys, to the southern Appalachians could reach 3 to 6 inches, with isolated amounts up to 8 inches. Rainfall totals for portions of the mid-Atlantic to New England could reach 2 to 4 inches, with isolated amounts up to 6 inches possible. This will be the last blog post on Hurricane Nate, additional updates will be on the Facebook page.
