Arthur is poised to become a hurricane and a fairly significant one at that. The NHC is forecasting winds to reach at least 90 mph before the cyclone transitions in to a more mid-latitude type storm. This has prompted the issuance of a hurricane watch for portions of the North Carolina coast – specifically from Bogue Inlet to Oregon Inlet. This encompasses all of the Crystal Coast and Outer Banks region. The time to prepare is at hand.
The hurricane watch is flanked on its north and south sides by a tropical storm watch as conditions look to deteriorate over the next day or so moving from south to north.
The storm strengthened overnight and now has winds of 60 mph as the pressure has dropped to 996 millibars. This represents a substantial reduction in air pressure over the last few days considering that the weak low pressure area emerged in to about a 1016 millibar environment. This tells me that the storm has potential to keep on strengthening once it rids itself of the pesky dry air and develops deep convection around its center. Warm water and light winds aloft could allow Arthur to become strong, possibly stronger than the forecast indicates. I always caution people who are dealing with hurricanes to prepare for one category higher – might as well be ready, right?
Right now, the storm is moving northward but the key time is when it makes the turn more to the east.
Even though the effects extend out well away from the center, it is going to be extremely important for the residents and visitors of the Outer Banks, especially Ocracoke and Hatteras, just how close the eye tracks to them. The reason is the storm surge from Pamlico Sound. If the radius of maximum winds moves over the sound then a storm surge exceeding 5 feet is possible on the north side of Hatteras and Ocracoke. This is where every mile will count. The closer the core of Arthur tracks to land, the more wind will push the sound southward, piling up the water against the land. It could mean the difference between “wow, that was close” and “wow, there’s a lot of damage here!”
Since there is no way to know even this close to the event happening, it is best to assume the worst. People in the area who have hurricane experience will know what to do. Visitors and newcomers may think this is a novelty and somewhat exciting. It is but that comes with a price. Storm surge is nothing to mess with. It can obviously be lethal but it also causes damage to automobiles and structures alike. Sound side flooding sneaks in – pours down Highway 12 and fills up Hatteras like a shallow basin. Don’t believe me? This is what hurricane Alex did in 2004.
I know because I shot this video. That is 105 mph wind coming across the sound pushing the water on to Hatteras. While no loss of life occurred, damage was extensive, especially to cars and trucks. Take this seriously folks, no two hurricanes are ever the same and comparing Arthur to Alex could be a big mistake. Take Arthur at face value and prepare accordingly.
For interests north and south of the hurricane watch area, the impacts will be less severe but they too should be taken seriously. It’s all about common sense which seems to be lacking more and more these days. The ocean will turn rough, stay out unless you’re an expert swimmer or surfer. Be careful driving in the torrential rains that are certain to fall along a wide swath as Arthur moves by. In short, don’t do anything dumb. Tropical storm conditions can bring trees down and knock power out. Take it easy, respect the storm and you’ll do fine. Take some pictures, share your experience on social media but do so with safety in mind.
I am preparing to head to the Outer Banks later today and plan to meet up with long time friend and colleague, Jesse Bass. We will be setting up one of our high-end weather stations which will feed wind and pressure data to our app, Hurricane Impact. The station also has a camera that sends an image from the site location every 60 seconds. You’ll be able to literally watch the impact of Arthur (that’s why we call it Hurricane Impact).
We will also post video reports to the app on a regular basis. So if you cannot watch our live Tahoe cam feed, you can at least stay up to date via the video reports which get posted minutes after we shoot them.
We will also deploy, if conditions warrant, four storm surge cameras. These are our unmanned camera systems that capture and stream live video from places that we have no business being in. These will feed to our private clients who support our work with their subscriptions to our suite of hurricane information and live video feeds. We will always have the Tahoe cam, also known as the “everywhere cam”, available on our Ustream channel free of charge. We’ll literally take you in to the worst conditions that Arthur brings to the area. Along the way, you’ll learn a lot about how tropical cyclones work, their impacts, history and so much more. It’s like a live science show during a hurricane – nothing else like it anywhere. I hope you can watch the free stream and consider signing up to catch our Surge Cam feeds as well. The mission is to gather data and document the impact. We are as ready as we have ever been in our 15 year history.
I’ll post another update later tonight on this page with continuing shorter posts on Twitter and Facebook.
To follow us on the go on your iOS or Android device – search Hurricane Impact and you’ll be good to go. It’s the only hurricane app that actually takes you in to the storm you’ve been tracking.
