Hanna Update

Tropical Storm Hanna is currently spinning off the northern coast of Haiti. It's expected to cause deadly flash flooding and mudslides across Hispaniola today. We are expecting Hanna to regain hurricane strength late tonight or tomorrow.

The storm will make landfall late Friday or early Saturday near along the South Carolina coast. I think the best timing for rain for us will be late Friday afternoon and early Saturday. Expect heavy rainfall and periods of severe weather especially east of Interstate -95.

Hanna Still On Track

This evening's data is still very consistent with the track of Hanna. For this reason, I feel confident increasing our rain chances for Friday and Saturday. I had a professor in college that told me to never give a forecast with 100% or 0% chance for rain. He reasoned that things can always change in the future. For this reason, I have put an 80% chance for rain on Friday and 70% on Saturday. Showers should start to taper late in the day on Saturday as Hanna races up the east coast.

Rainfall In The Past Week

Here is a map that shows rainfall over the past week. Most of this rain was associated with remnants of Fay. Notice how the eastern half of the state missed out on most of the rain.

Here is another map with stream and river data. Blue dots represent flow that is above normal, where orange/red dots are below normal. Green dots show normal flow. Last week, most streams and rivers were flowing well above average, but now a lot of them are back below normal.

It's nice to see that the ground isn't too saturated from Fay's rains. This is good news considering that remnants of Hanna could also produce some flooding in the area.
