Thunderstorms roared across Florida on Nov. 5, with damaging wind gusts and torrential rain that led to severe flooding.
A storm that already has a history of producing flooding rainfall across the southern Plains and Southeast Florida will continue it's path eastward off of the Southeast coast on Sunday. Parts of the Sunshine State faced soaking downpours and severe wind gusts on Friday, during what is typically the driest month of the year, and the Southeast endured additional coastal hazards as high tides elevated the flooding threat on Saturday.
On Friday, cold air poured across the Southeast ahead of the advancing storm, and as it pressed southward, this chilled air collided with a warm and humid air mass situated over the Florida Peninsula. The collision allowed a front to set up along the Gulf and Atlantic coastline that served as the path for the drenching storm.
As the storm came together over the Gulf of Mexico, rain and thunderstorms reached the Florida Peninsula by Friday morning. By later Friday morning, heavy rain and torrential downpours had spread across much of the Sunshine State.
According to local observations, Sanibel, Florida, reported a whopping 3.05 inches that fell in a six-hour period ending at 5 a.m. Friday.
By Friday evening, locations such as Daytona Beach Shores, Florida, had reported a 24-hour rainfall total of 9.27 inches. Storms continued to bring rainfall to portions of Florida through the overnight hours on Friday.

"November is the driest month of the year in a large part of Florida, and rainfall amounts from this storm could reach, and even double, average monthly November levels," said AccuWeather Senior Meteorologist Dave Houk.
The wet pattern continued its path farther east on Saturday, bringing rounds of rainfall to northern Florida and the Carolina coastlines.
In Daytona Beach, Florida, the normal amount of November rainfall totals at 2.76 inches. With only six days of rainfall reported so far this November, the city had already reached roughly 228% of their monthly precipitation. The majority of this rainfall was recorded on Friday and Saturday as the storm passed over the Florida peninsula.

Thunderstorms also brought the threat of damaging wind gusts and isolated tornadoes to the Florida Peninsula through Friday evening. In Aberdeen, Florida, a severe wind gust report of 60 mph was submitted to the Storm Prediction Center (SPC) as a result of the storms that rolled through South Florida on Friday.
As the potent storm continued to pivot from northern Florida to the Southeast coast on Saturday, some coastal areas experienced gusty winds that whipped up rough surf and brought the threat of strong rip currents. These coastal impacts targeted the west-facing coasts of Florida on Saturday, as gusty winds turned westerly behind the storm. To the north, north and easterly winds infiltrated the coast from the Carolinas to the Jersey Shore on Saturday.
Another factor came into play, particularly in the Carolinas, which led to significant coastal flooding. Higher-than-normal tides known as king tides have been impacting the Southeast coast since the end of the previous week. The very high astronomical tides, which on their own cause minor coastal flooding, along with the onshore flow and rough surf from the storm enhanced coastal flooding from the storm.
"Places like Charleston, South Carolina, and Savannah, Georgia, could have flooded marinas as well as streets and buildings right along the coast for a period of time," AccuWeather Senior Meteorologist Brett Anderson said.
As heavy rain reached the Carolina coastlines on Saturday, residents were warned that flooding could be exacerbated, especially at high tide, as rainwater isn't able to run off into the ocean effectively. A general 1-3 inches of rain was expected to fall along and near the Georgia and Carolina coastlines through this weekend, with isolated higher amounts possible along the immediate coast. Rain will exit east of the Outer Banks late Sunday.
Meteorologists warned that flooding on roadways in heavy downpours was likely and could lead to travel delays. Where tidal flooding covers streets near the coast, drivers are reminded to wash their cars, as the salty ocean water can cause corrosion if not washed off.
"It's like northern areas that deal with salty roads in the winter time," explained AccuWeather Senior Meteorologist Dan Pydynowski. "The water evaporates and can leave a layer of salt on the undercarriage of the car, which over time causes rust and corrosion if not removed."
AccuWeather tropical forecasters say the storm may have another trick up its sleeves.
"There is a small chance this evolving storm system could acquire some tropical characteristics through Monday as it moves over relatively warm water and becomes detached from the frontal boundary," Pydynowski said. "If this were to happen, it could be classified as a subtropical storm for a brief period of time."
If the system becomes organized enough to be named a subtropical storm, which has both tropical and non-tropical features, it will be given the name Adria by the National Hurricane Center. That is the first name on a supplemental list created by the World Meteorological Organization last spring as a replacement for the Greek alphabet, which meteorologists previously used to name tropical storms once the designated list of names was exhausted.
Wanda, which developed over the weekend and continues to meander around the Atlantic on Sunday, was the last name on the original Atlantic name list for 2021.
The expected impacts are not expected to change should Adria be named.
While this storm affects coastal portions of the Southeast, the majority of inland regions will hardly even be able to tell that there's a storm nearby. A large area of high pressure across the rest of the region will lead to a dry and rather sunny end to the week. Most of the Southeast will top out with highs in the 60s and 70s F on Sunday.
By Sunday night, the coastal storm will have moved out of the region, and the moderating temperatures across the Southeast will last into next week.
High pressure will move into the region once again and dry out much of the Florida Peninsula where residents can have the opportunity to clean up any storm damage that ensues.
