Because the world flips the calendar to 2021, many residents could take time to replicate on the yr now solidly within the rear-view mirror. The yr 2020 was for a lot of, however one factor is for positive: many heavy rain occasions took goal on the southeastern United States.
In a soggy yr for a lot of the southeastern U.S., a few of the most prolific occasions got here because of tropical exercise.
The 2020 Atlantic Ocean hurricane season was actually report breaking. An unprecedented 30 named tropical programs roared to life within the basin, a report shattering 12 of which made landfall on U.S. soil. A number of of those land-falling tropical programs adopted a storm monitor that introduced a deluge of rainfall to the southeastern quarter of the nation. Delta and Zeta have been two notable examples of this phenomenon.
Due partly to those tropical strikes and a end result of many potent non-tropical storms all year long, many areas from japanese Texas by the Southeast and up into the mid-Atlantic skilled above-average rainfall totals in 2020.
The yr 2020 was the third-wettest yr of the previous 10 years for Atlanta, with solely 2018 and 2015 recording extra rainfall. In 2020, the observing station at Hartsfield-Jackson Atlanta Worldwide Airport recorded a complete of 66.99 inches of rainfall, which was practically 17.50 inches above the yearly common for the positioning. Equally, 2020 was the second-wettest yr of the previous 10 years for Charlotte, North Carolina.
Whereas 2020 was an abnormally moist yr for a lot of throughout the southeastern quarter of the U.S., that pattern seems unlikely to alter for the primary month of 2021.
As an expansive storm system overspread a lot of the japanese half of the nation to ring within the new yr, heavy rain and powerful thunderstorms rocked parts of the Southeast. Whereas a common 1-Three inches of rain soaked areas from japanese Alabama to western North Carolina on Friday, at the very least one confirmed twister spun up in Georgia. Rain and storms continued for parts of the southeastern U.S. on Saturday.
Because of this storm, many areas throughout the southeastern U.S. have already obtained between 20% and 50% of the standard rainfall quantity for all the month of January. As of Sunday, Atlanta stands at 29% of its common rainfall for the month, whereas Augusta, Ga., stands at 50%.
Many of those areas are on tempo to exceed typical precipitation ranges for the month of January. One such location, Columbia, S.C., takes this concept to the intense. Within the first two days of 2021, the town has already recorded 2.53 inches of rainfall, or 71% of its common rainfall for all the month of January, with a number of weeks to go.
Forecasters say that the atmospheric sample is such that rounds of moist climate are more likely to goal the southeastern portion of the nation all through the month of January.
“A robust space of excessive stress over japanese Canada and Greenland, often known as a ‘blocking excessive’ and weakening polar vortex can start to affect the sample late this week,” AccuWeather Senior and Lead Lengthy-Vary Meteorologist Paul Pastelok defined. “This may proceed to pressure a really lively southern storm monitor.”
“The South and Southeast will take care of extra stormy climate and lower-than-normal temperatures, which may final by the remainder of January,” Pastelok stated.
