Tropical Storm Warning now in effect for Floyd, Chattooga and extreme Northwest Georgia (Dade, Catoosa and Walker).
A Tropical Storm Watch continues for Bartow, Polk and Gordon.
A flash flood watch is in effect from Sunday afternoon into Monday morning for most of Northwest Georgia.
9:30 p.m. update from NWS: The chance for a few showers and thunderstorms will increase this evening from the south as Nate approaches the northern Gulf coast. Some storms could be strong with gusty winds and locally heavy rainfall as the main threats. Periods of showers and thunderstorms will increase Sunday in association with Tropical system Nate. Some storms could be strong to severe with brief, spin-up tornadoes, damaging winds, and locally heavy rainfall. In addition, a Flash Flood Watch is in effect for portions of north Georgia, Sunday afternoon into Monday morning, with 3 to 5 inches of rain expected. Power outages can also be expected, mainly in northwestern Georgia where winds will be the strongest. Keep in mind that Nate covers a large area and tropical storm conditions can occur outside of the narrow “cone of uncertainty.”
Rain and possible tornadic activity will begin before the arrival of the strongest winds, and continue throughout the event. Rainfall will begin tonight as the storm approaches and continue into Monday. The threat for tornadic activity will increase overnight Saturday and last through Monday morning. The strongest winds are expected to arrive on early Sunday and remain until early Monday morning.
HURRICANE LOCAL STATEMENT- SITUATION OVERVIEW
(As of 9:30 p.m. Saturday) Hurricane Nate continues to progress north northwest over the Gulf of Mexico and is expected to make landfall along the northern Gulf coast overnight tonight. Weakening is expected after landfall, and the storm is expected to track across Alabama and northern Georgia as a Tropical Storm through Sunday and Sunday night. It should be noted that impacts from heavy rain and potential tornadoes will precede the most significant winds with this system and are possible as early as tonight.
During the height of the storm, winds of 30 to 40 mph will be possible with gusts as high as 50 mph across far northwest Georgia. Storm total rainfall is expected to be on the order of 3 to 5 inches north of a line from Rome, to Dawsonville, to Homer with locally higher amounts possible.
* WIND: Protect against hazardous wind having limited impacts across portions of northwest Georgia. Potential impacts in this area include:
– Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about.
– Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over.
– A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways.
– Scattered power and communications outages.
* TORNADOES: Protect against a tornado event having possible limited impacts across NORTH AND CENTRAL GEORGIA. Potential impacts include:
– The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events.
– A few places may experience tornado damage, along with power and communications disruptions.
– Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings.
* FLOODING RAIN: Protect against dangerous rainfall flooding having possible significant impacts across portions of North Georgia. Potential impacts include:
– Moderate rainfall flooding may prompt several evacuations and rescues.
– Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots. Small streams, creeks, and ditches overflow.
– Flood waters can enter some structures or weaken foundations. Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. Some road and bridge closures.
