The 2023 hurricane season has arrived and forecasters are expecting a near-normal season ahead. That means we can expect to see tropical storms, hurricanes, and major hurricanes in the Atlantic basin.
Even though Central Georgia is not on the coast, we can see our fair share of impacts from tropical systems. In fact, the biggest flood in Central Georgia history came from a tropical storm in 1994. Not to mention, the devastating agriculture economic impact from Hurricane Michael in 2018.
Here's what you should know for the 2023 hurricane season.
NAMES
Names from tropical systems are determined by the World Meteorological Organization and are recycled every six years. If a storm is devastating enough, a country can request that a name be retired and never be used again. The United States did this in 2022 with Hurricane Ian.
Here are the names for the 2023 season.
Arlene
Bret
Cindy
Don
Emily
Franklin
Gert
Harold
Idalia
Jose
Katia
Lee
Margot
Nigel
Ophelia
Philippe
Rina
Sean
Tammy
Vince
Whitney
This list was most recently used in 2017. The names Harold, Idalia, Margot, and Nigel replace Harvey, Irma, Maria, and Nate.
Hurricane Harvey brought devastating wind impacts to the Texas coast and widespread flooding to the Houston metro area. 13WMAZ's sister station, KHOU, was even flooded out of their studios and had their signal knocked off the air. The United States requested the name Harvey be retired.
Hurricane Irma made landfall in southwest Florida, came up the peninsula, entering central Georgia and causing widespread damage while doing so. The United States requested the name Irma be retired.
Hurricane Maria struck Puerto Rico as a high-end category 4, knocking our power to most of the island and even the radar used to monitor the storm. Many in the US territory are still feeling the impacts from Maria today. The United States requested the name Maria be retired.
FORECAST
NOAA forecasters are expecting a near-average season with 12-17 named storms, 5-9 hurricanes, and 1-4 major hurricanes. The government agency has 70% confidence in this forecast.
Dr. Philip Klotzbach, a forecaster specializing in Atlantic basin seasonal hurricane forecasts at Colorado State University, agrees with 13 named storms, 6 hurricanes, and 2 major hurricanes.
In 2022, we saw 14 named storms, 8 hurricanes, and 2 major hurricanes. It's worth noting that the season started on a quite note with only three named storms between June and August. Most of the activity came in the fall, after September 1.
A big change from last year - La Niña is no more. Waters in the equatorial Pacific ocean have warmed, causing wind shear to be not as conducive in the Atlantic for development. Just because La Niña is over does not mean El Niño immediately takes over. We will be in a neutral phase for the short-term, entering hurricane season.
THE CONE
The iconic forecast cone shows the potential track for the center of a tropical cyclone. The National Hurricane Center uses forecast error from past years to determine the cone's width at different forecast time. The storm is expected to stay in the cone two-thirds of the time, and track outside of the cone one-third of the time.
Bottom line, the cone does not show where impacts are expected, only the where the center is forecasted to go. Even then, the expectation is that the center stays within the cone only two-thirds of the time.
