Hurricane Florence Warning for Grape Growers

— Written By

Dear Grape Community,

Many of you have asked me over the last few days what to do to prepare for the incoming Hurricane. My advice is as a general rule, if you live close to the coast in Eastern North Carolina, and you are close to harvest, pick as many grapes as possible before Thursday afternoon. Especially close to the Coast, it is likely that you will encounter high winds and a lot of rain. The high winds might be a threat to your trellis systems. In the Piedmont and Triangle area, winds will be slower, but heavy rains are expected. Tall current is expected at the Coast.

If you and your family are ordered to evacuate, please follow those orders! It is for your own safety.

Here an update on Hurricane Florence:

A. The Situation

Hurricane Florence is approaching the Carolina Coast. Currently, it is a Category 4 Hurricane and will make landfall sometime between Thursday afternoon and Friday morning at the Carolina Coast.

Please see Figure 1 – 3 for current prediction models on path and strength

C. What to Do?

First and foremost, you and your family should be safe. Prepare yourself, have enough food and water at home, have batteries, flashlights and a radio. Please visit our Disaster Information Center to gain updates and information on how to prepare for the incoming Hurricane.

If you are in an affected area and you are close to harvest, you better harvest now! The Piedmont region also will be affected, mainly by heavy rains.

Some growers asked me if it would make sense to thin out the canopy. Since this is also my first Category 4 Hurricane, I can’t give an experienced advise. My guess is, that, if you have the time to do it, and you are already through your harvest, it definitely would help to reduce the possibility for the strong winds to damage your trellis systems and your vines.

Please stay safe over the next days and don’t hesitate to contact me or any of your county agents at any time.

Thanks,

Mark
