CHARLOTTE, N.C. — A Tropical Storm Warning has been expanded in Charlotte and Mecklenburg County ahead of impacts forecasted Thursday from Zeta.
The warning, which had already been issued earlier Thursday for western parts of North Carolina and upstate South Carolina, has been expanded eastward to include more of the metropolitan area.
A Tropical Storm Warning means tropical storm-force conditions are highly likely for Thursday.
As of 5 p.m. Wednesday, the warning included but was not limited to: Mecklenburg, York, Cabarrus, Rowan, Gaston, Lincoln, Catawba, Cleveland, Avery, Burke, Alexander, and McDowell counties.
Zeta’s Louisiana landfall
As of 5 p.m. Wednesday, Zeta was a category 2 hurricane making landfall south of New Orleans, Louisiana.
The tropical storm system is expected to maintain tropical storm strength as it moves quickly across the Southeast and through the Carolinas Thursday. This will be a quick-moving system which will keep the winds still relatively strong by tomorrow morning.
Wind impacts from Zeta in the Carolinas
A storm is considered to have tropical storm strength if it has sustained winds of over 39 mph. Gusts could be higher.
Morganton, Hickory, Lincolnton, Statesville, and Gastonia could be among the areas that see 30 to 40 mph sustained winds with gusts up to 50 mph.
Higher, mountains elevations near Boone and Blowing Rock could see sustained winds of 25 – 35 mph with gusts up to 45 mph.
South of Interstate 85, including the City of Charlotte, Rock Hill, and Fort Mill, could see winds of 30 mph with gusts up to 40 mph.
As a result, scattered power outages and down trees are possible as Zeta impacts the region a Thursday.
Increased winds are expected to arrive in the early morning hours of Thursday before rapidly diminishing Thursday night.
Rain and flooding impacts from Zeta in the Carolinas
Zeta is forecast to bring 3 – 4 inches of rain to the higher elevations in the North Carolina mountains, including in Avery, Ashe, and Watauga counties. Rainfall totals decrease with elevation with 2 to 3 inches expected near Lenoir. Across the foothills and mountains, the National Weather Service has issued a Flash Flood Watch, which means flash flooding could occur over the next day.
In other parts of the foothills and piedmont, 1.5 to 2 inches of rain could be observed in Hickory, and upwards of one inch in Charlotte.
Although a tropical storm watch has not been issued for counties such as Mecklenburg, Avery, Ashe and Watauga, residents should monitor changing weather conditions over the next few days.
Tornado impact from Zeta in the Carolinas
And while Zeta’s strongest winds and highest rainfall rates are expected in the higher elevations of the Carolinas west of Interstate 77, there is a low risk potential for severe weather along the Interstate 77 and Instate 85 corridors Thursday.
Cities like Charlotte, Statesville, Columbia, and Greenville, could see an isolated tornado risk early Thursday morning through Thursday afternoon.
Across the Southeast and Carolinas, residents are encouraged to charge batteries, phones, and radios ahead of Zeta. Scattered power outages are possible Thursday.

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.
- FLOODING RAINS: Potential for localized flooding rain. Rivers and tributaries may quickly rise with swifter currents. Small streams, creeks, canals, arroyos, and ditches may become swollen and overflow in spots. Flood waters can enter a few structures, especially in usually vulnerable spots. A few places where rapid ponding of water occurs at underpasses, low-lying spots, and poor drainage areas. Several storm drains and retention ponds become near-full and begin to overflow. Some brief road and bridge closures.
