Hurricane Sally could generate “historic and deadly” floods from Mississippi to the northwest coast of Florida due to the large amount of rain that would accumulate due to its translation movement of just 2 miles per hour (mph), according to the National Hurricane Center (NHC, in English).
The meteorological agency established in its most recent discussion that in concentrated areas inland the accumulations of water could be around 10 to 20 inches, while in isolated areas the accumulations could exceed 30 inches of rainfall.
“Historic flooding is possible with extreme life-threatening flash floods through Wednesday along and just inland along the central Gulf Coast from the Panhandle in western Florida to southeastern Mississippi. Generalized moderate to large floods are forecast in areas near rivers and just in the area of the interior of the central Gulf ”, detailed the NHC in its report.
“Significant and urban flooding as well as minor to moderate river flooding are likely in portions of Mississippi, Alabama, North Georgia and the Carolinas throughout the week, ”he added.
In the 7:00 am report, the NHC indicated that Sally was at latitude 29.1 degrees North, longitude 88.0 degrees West and moving northwest at 2 mph, with sustained winds of 85 mph.
According to the National Meteorology Service meteorologist Gabriel Lojero, the reason behind the historic flooding of this system is not only due to its slow movement, but the area where the eye of the hurricane is expected to make landfall is surrounded by rivers.
“In that area there are rivers that can help the development of floods. So by moving very slowly, obviously it is going to rain for a long time and that is going to create significant and extreme accumulations. For a tropical cyclone in that area, Sally would be the storm that would produce the most amounts of rain “, highlighted the expert.
“Right now it’s raining and that should continue until Wednesday. Already on Thursday as the system moves over the southeastern states of the United States it could also rain. For example, in the Carolinas, 4 to 6 inches of rain could accumulate, ”he added.
Meanwhile, the NHC warned that floods would not be the only threat to these sectors, but there are also warnings for tornadoes and for the storm surge that the cyclone will generate.
Warning zones range from southeastern Louisiana to the Florida Panhandle.
“Residents in these areas should follow any advice from local officials,” the NHC noted.
Sally is one of 7 hurricanes that have formed during this hurricane season.
