Debby Morning Thursday (8 Aug) Update

The “center” of an increasingly asymmetric Debby made landfall this morning and is starting to move a bit faster. Here’s the current IR satellite since it’s still dark at 5:30am …

The radar shows this as well, the heavy rain bands well north of the center and arcing across most of North Carolina …

And, if in Savannah, you can go out and see these bright points in the sky known as “stars”!

The forecast – best summarized in NHC’s Key Messages regarding Tropical Storm Debby (en Español: Mensajes Claves) – is for Debby to begin moving faster and curving across the Northeast over the next three days before merging with another system over Canada. Here’s the impact swath …

In the southeast, the “second disaster” that typically follows a heavy rain event is getting underway. Here is are the rain totals for the last three days (72 hours ending 5am ET this morning).

All that rain, including that which was able to soak in or enter creeks and rivers, is now trying to flow to the sea, and anything in the way is going to get flooded. As noted yesterday (link), another issue are dams and other catchments are failing or have failed, contributing to the problem. So while it will likely be sunny this morning in coastal Georgia and the Lowcountry, the impact of Debby continues and some areas are still flooded.

The air is still quite wet, and there is forcing that may trigger thunderstorms this afternoon. Given the saturated conditions and potentially debris clogged drainage system, it won’t take much to cause flooding, so be careful.
