Debby Update Wed. Evening (7 Aug 2024)

Tropical Storm Debby is is trying to make landfall again, this time between Charleston and Myrtle Beach. But it’s still not exactly moving fast …

The latest NHC bulletin has Debby as a 50kt storm, but that’s not really descriptive given the organization of the system. As you can see from the animation the storm lacks a core. Here’s links to the official Key Messages regarding Tropical Storm Debby (en Español: Mensajes Claves), and here is my TAOS(tm) TC impact analysis map of that forecast:

The story remains rain. It’s still raining heavily in some places, but it’s a lot less extensive than yesterday:

Additional rainfall will mostly be north of the Frogmore metroplex (Beaufort), although scattered rain will probably continue through Thursday hopefully it won’t be heavy. There is still extensive flooding across mainly inland areas of Georgia and South Carolina – in comparison, close to the coast suffered less. Many counties such as Bulloch (Statesboro) are recommending that people stay off the roads. In most of the inland counties you won’t have much choice in some cases: dirt roads are all virtually impassible. Damage reports are still coming in, a quick look at the NWS Local Storm Report data base (which appears well behind) shows a rash of icons across the region …

Unfortunately for those downstream of the flooded areas things are going to get worse before they get better, as all that water runs off and ends up in creeks and rivers. Another factor is that many of the smaller earthen dams in the area are overflowing and at risk of erosion or outright collapse. Given all that, It’s sobering to consider that rainfall totals are only 50% to 70% of what was forecast.

So while the weather event is coming to an end across Florida, Georgia and the Lowcountry of SC, the consequences have not, and the cleanup and damage assessment is just really getting underway. And Debby has more rain and some wind to deposit across northern SC, North Carolina, and likely Virginia before it’s all over.
