Hurricane Irma Weakening, less of a threat to Tennessee

The latest (and final) advisory related to Hurricane Irma basically indicates that the biggest threats are from rainfall, and even then little flooding is expected in East Tennessee.
This will be the last update briefing from NWS Morristown concerning Tropical Storm Irma.
Winds will increase through the day. We have highlighted the winds with the Wind Advisory. Look for winds of 15-30 mph with gusts of 40-50 mph. Highest winds and gusts will occur in the higher elevations. Highest wind gusts will occur tonight. Trees and power lines will be most susceptible to the higher winds. Therefore, a few power outages could occur. Winds will begin to subside Tuesday afternoon.
Rainfall does not look to be a problem. Around 2″ of rainfall is expected along and south of a Dayton, TN to Clay County NC line. Less rainfall is expected north of that line (generally north of I-40).
All rivers in our forecast area will remain below action stage, including the highlighted rivers from past briefings (Nolichucky, Pigeon, and French Broad). The rainfall in NC is expected to be less than previously forecast.
East Tennessee may have dodged a bullet with Irma, but as always, with a rain / wind event, use caution.

Hurricane Irma closing in on Florida Keys, coming into Tennessee next Tuesday

As of this posting, Hurricane Irma is back to a Category 5, with 160MPH sustained winds.

Overnight last night it moved on a more westerly track, putting its eye over the Florida Keys and the Gulf side of Florida’s peninsula.

It is still projected to strike Florida as a Category 5, or a high Category 4 when it makes landfall.

As of 11PM EDT on 9/8/2017, LOCATION: 22.1°N, 77.7°W – 120 mi ESE of CAIBARIEN CUBA.

As it makes its way north through Florida over the weekend, East Tennesseans will want to pay attention early next week as forecast models have the remnants of Irma over northern Georgia and/or Alabama and into Tennessee late Monday through Tuesday. In some models, the center of Irma could come into Tennessee, drift West, then turn towards the East, possibly bringing tropical storm-force winds, and dumping torrential rainfall in the area and causing flooding issues as it changes directions.

Irma’s death toll stands at 22 but it may climb as it makes partial landfall in Cuba before crossing into Florida.

Stay tuned to your local television and radio outlets, listen to NOAA Weather Radio for the latest, and listen to East Tennessee SKYWARN on 146.940 (alternate 146.625 MHz) as conditions warrant.
