North Florida, South Georgia stuck between two tropical systems
August 28, 2017
TALLAHASSEE, Fla. (WCTV) --The National Hurricane Center has marked an area of low pressure off the Georgia coast as “potential tropical cyclone 10.” The wording may seem elaborate, but it means that this disturbance could become a tropical storm very soon. Because of its close proximity to land, this designation will allow the National Weather Service to issue tropical storm watches before the disturbance reaches tropical storm strength.
If this disturbance develops into a tropical storm as expected, it will be Irma.
As of the 11AM advisory, the potential tropical cyclone is expected to reach tropical storm strength by Tuesday. Winds within that area of low pressure already have speeds of 35 mph. Tropical storm watches and warnings extend along the North and South Carolina coasts. The storm will move northeast into the Atlantic again.
Along the Gulf coast, Harvey remains a tropical storm with winds of 40 mph. The storm is slowly moving around 5 mph. Harvey brought catastrophic flooding to Texas. More than two feet of rain were measured in some spots over the weekend. Models indicate several more inches of rain through Thursday, as Harvey moves northeast toward Central Louisiana.
Both Harvey and the disturbance off the Atlantic coast will influence parts of the local forecast. The disturbance in the Atlantic is located to the northeast of our coverage area. Circulation around that area of low pressure will bring in winds from the northeast as well. This is providing a less humid feel to the air on Monday and could make conditions a bit breezy at times. Rain associated with the disturbance is not expected to be part of the forecast on Monday. Only a few showers could move in from the east. A weak front stalled to the south of the Big Bend will linger over the area. Harvey will remain well to the west, but moisture from the storm and winds taking a southerly turn along the stalled front will help increase rain chances by Wednesday. Rain chances will then linger around 40% to 60% through Sunday.
