Hurricane Laura is currently undergoing rapid intensification in the Gulf of Mexico and could strengthen before landfall to a high end Category 4 storm. Models suggest that landfall will be likely around Port Charles, LA sometime late this evening or early tomorrow morning. A modern day ghost town can be found in locations under Hurricane Warnings because citizens are taken this storm seriously, as they should. Below you can see the most recent satellite imagery form GOES-16 of Hurricane Laura.
How Will Laura Affect WNC?
On Saturday expect scattered showers from an approaching remanent low of what is left of Laura. A unique phenomena could develop as Laura sweeps East known as a Sting Jet. A sting jet manifests when there is rapid development in the mid latitudes. As Laura transitions to a post tropical storm, this will happen over land and a strong mid latitude cyclone will be the result. Check out the European model depiction I have shown below. You can see Laura making landfall and then being picked up by the Jet Stream. As the storm decouples and loses its vertical structure, a stout post tropical storm will develop.
What Does This Mean For WNC?
Well there is still some uncertainty as to how this event unfolds, I believe that a high wind event is on tap for WNC, especially in the higher elevations Saturday. Winds could gust over 50mph in some locations as the remnants of Laura pass by. I am waiting on short range model data to resolve the solution, but for now notice how the winds increase on the European model late Saturday night below.
Main Story
The wind from this event will be the main story. Most models limit rainfall to less than 1.5” across WNC, so flash flooding will likely be kept at bay expect for isolated locations. It would be wise on Saturday morning to secure outdoor accessories that are susceptible too wind. Report your high wind gusts to the AshevilleWX Weather Community and check back later today or tomorrow, I will do a live update.
