The Sequatchie Valley prepares for impacts from Hurricane Nate’s remnants

Nate Update — Sunday 1:40pm:

Good news regarding Nate. The National Hurricane Center has downgraded Nate from a Tropical Storm to only a depression. Locally, all Tropical Storm Watches and Warnings are cancelled. A Wind Advisory and for some a Flash Flood Watch remains in effect.

Changes to timing and overall impact:

Nate continues to move quickly north and east through Alabama. A dramatic weakening trend did occur prior to landfall last night, which has caused a much weaker Nate than forecast inland. Because of this, less wind and tornado impacts are expected (though gusty winds up to 35 mph may still be possible).

Because Nate continues to move quickly and radar indicates rainfall is only occurring to the north and east of the center, rainfall amounts have also been lowered to 1-3 inches with locally heavier amounts. There will still be a limited flash flooding threat as Nate continues to push through this evening.

Although we aren’t completely out of the woods with Nate, it appears from an impacts perspective, a decrease in overall risks has occurred since our last update late last night.

Previous Update: 

The 2017 Hurricane Season has been one of the more active seasons on record in the past few years, with the U.S. already seeing the devastation left behind by Hurricane Harvey in Texas and just days later Irma in Florida, but now we see the Gulf Coast from Louisiana to the Florida Panhandle preparing for yet another tropical system making landfall.

Hurricane Nate Update 6pm CDT 10/7/2017:

Current Watches/Warnings/Advisories:
Wind Advisory in effect for much of eastern Tennessee and northeast Alabama including Marion County. Sunday and Sunday Night. A Wind Advisory means winds of 39-57mph expected.

Tropical Storm Warning for all of northwest Georgia. A Tropical Storm Warnings meanings Tropical Storm Conditions (sustained winds greater than 39mph) expected within the next 24-36 hours.

Flash Flood Watch for northeast Alabama and northwest Georgia through late Sunday.

What to expect:
Showers and perhaps a thunderstorm or two will begin later tonight as moisture from Nate meets a cold front moving toward our area from the northwest. The chances of widespread showers will be possible later tonight and into Sunday. As Nate moves northward through Alabama and into Tennessee, rainfall will becomes heavier by Sunday afternoon. Flash Flooding will become a concern beginning late afternoon on Sunday through early Monday morning.

Winds will gradually increase from the south. Generally, many of us are looking at sustained winds up to 25mph, however, gusts could top 40-45mph in the valley and gust up to 45-50mph in the higher elevations. Winds of this magnitude may push over shallow rooted trees and snap branches. This may potentially cause some power issues.

Landfalling tropical systems often produce brief quick spin-up tornadoes. There will be a threat for tornadoes Sunday midday through early Monday morning.

The primary impacts:

  • Flash Flooding is the biggest concern followed by slower response river flooding. Around 3-5 inches likely. Up to 7 inches of rain can’t be ruled out.
  • Power outages due to limbs and trees toppling onto electrical lines
  • Brief/weak tornadoes.
  • Be sure to secure outdoor furniture, trashcans, Halloween decorations, and/or other light weight objects that may blow around in strong winds.

Previous Update 7:15pm 10/6/2017

Tropical Storm Nate is currently between Cozumel, Mexico and the western tip of Cuba moving north northwest at 22mph toward to north central Gulf Coast. Nate is expected to become a hurricane later tonight or early Saturday. It should make landfall near Pascagoula, MS early Sunday morning as a Category 1 hurricane.

The remnants of Nate will move into our area by Sunday evening. The storm will be moving quickly, however, torrential rainfall is expected for our area. Flooding may become a concern with tropical rainfall rates. Additionally, strong wind gusts up to tropical storm force may be possible especially in the highest elevations. These winds may blow over trees and blow around items such as holiday decorations and trash cans. There is also a chance for quick brief spin-up tornadoes along and east of the center of the storm.

Previous Update:

According to NOAA’s National Hurricane Center, Tropical Storm Nate is expected to make landfall along the north central Gulf coast as a Category 1 hurricane this weekend between late Saturday night or early Sunday morning packing lots of rain and winds in up to or in excess of 70 miles per hour.

What does that mean for our area? Currently the remnants of Nate look to travel north and northeastward toward the Tennessee Valley by early next week. While we could see some showers late Saturday afternoon and evening, the most notable impacts locally should begin Sunday and last through early Monday.

Thankfully, this system will be fast moving, so flooding threats will be a bit lower; however still possible. In addition to flooding there may be some gusty winds and if we are on the eastern side of the storm (as currently forecast) there will be a threat for a brief spin-up tornado or two.
