A Complete and Exhaustive Guide to Hurricanes – part four
The rainbands, the eyewall, and of course the eye of the hurricane are its main components. Surface air in a cyclone structure spirals in an anti-clockwise direction and then it starts to move upwards close to the center and flows out through the top in a clockwise direction. At the center of the hurricane is the mysterious and calm eye having a warm core and is cloud-free.
The eye of the hurricane is an area that is relatively calm and can be around 10 to 14 nautical miles wide. The eyewall surrounds the eye and is the innermost convection ring where some of the most severe winds and storms occur. This can have a width of around 10 to 15 nautical miles. The size and intensity of an eyewall has massive significance for the intensity and duration of a hurricane.
The rainbands are bands of storms that can extent as much as 500 nautical miles from the center of the storm. The rainbands serve an important function to move warm ocean water to the middle and upper troposphere and feed the cyclone.
Winds are a good measure of finding out the way to the center of a cyclone. Surface winds in a North Atlantic tropical cyclone will flow in an anticlockwise direction. Another indication to the location of the center of a cyclone is the direction of the swells in the open ocean. A swell to the south west of your vessel would indicate that the center of the hurricane was to the south west when the swell originated. Usually a swell lasts for 6-8 seconds in the North Atlantic; if it lasts for around 9 to 12 seconds then it is a fairly reliable indicator that the swell is because of a tropical system close by.
Clouds are also an indicator that navigators need to consider; to a ship that is anywhere between 500 to 1000 nautical miles from a tropical system the clouds will appear clear and cumulus clouds, if any, won’t have any great depth. At around 300 to 600 nautical miles the cirrus clouds appear as thin wisps that can be seen moving away from the center of the system. At 200 to 400 nautical miles, the rainbands appear, rain showers occur and thick walls of cumulonimbus clouds can be observed hanging very low.

Doc and Christy B. October - 2019 - Waynesville, Georgia
Hello again, it’s Christy B from Waynesville, Georgia. My husband and I have installed 6 out of the 9 roll shutters and we cannot say enough about them! The quality and workmanship is excellent, the shipping packaging was quite satisfactory and the fit is perfect. The shutters roll nicely and the installation video on your website is what we went by. After the first one’s learning curve, the rest have been no problem at all! We hope that you get some additional orders from up here as several of our friends and neighbors plus a local general contractor are anxious to check the shutters out. Our daughter in St. Augustine is jealous.....their subdivision builder used window storm panels and she hates manhandling them and storing them. Thank you Liz, Barbara, Mike, Bill and the rest of the staff. We are very, very pleased that we chose your product to protect our home.

Larry A. - March - 2019 - San Diego, California I am writing this email to say Thank You to everyone at Empire. I have just finished installing the rolling and accoridon shutters you shipped to me on order 26692.The quality of your product is excellent, and your delivery was shorter than expected. The care that was taken by the people that packaged my shutters is above and beyond, and greatly appreciated. The patience Michael Joiner and his sales team showed me over the weeks I was debating what kind of shutters to by, and from whom, was also greatly appreciated. I would be happy to be a reference here on the West Coast if you should ever want one. -Larry

My Accordion Shutters are up! The windows took about 1.5 hours each. The shutters all fit very nicely, the material and finish is excellent, and they look very good. They are not intrusive at all. I am pleased, my wife is pleased ( you know that is important) and my neighbor, who helped me was impressed based upon his window/door experience. Good job! Thanks.
Marcus J. - August - 2018 - St. John, U.S Virgin Islands Hello everyone at Empire, Marcus from St. John here. This project is being done by me and 1 helper, and we're going back much stronger, with many more tap cons, and wedge anchors than the original installers had done. Your rolling shutters are amazing, great quality and workmanship. Everything is going great so far!
David G. - July - 2018 - Sarasota, Florida
We wanted to self-install so we bought accordions and roll downs from Empire Construction.We measured our window and patio and sent Empire the specs.The shutters were an exact match.Installation is very doable for two reasonably mechanical people. In this case it was only one mechanical person and some extra hands. The accordions were a breeze as installation was mostly marking holes for spots, drilling holes, and screwing them in.Our accordions have locking pins that hold them open and act as a second lock when closed. Even if a projectile breaks the lock the rods will keep the shutters closed.These shutters are Bertha HV1. They are High Velocity Hurricane Zone Approved. Having seen a wide range of shutters we are extremely happy with the quality of the product we received!!
Jim J. - June - 2018 - Homestead , Florida
I installed fourteen aluminum accordion shutters which I purchased from Empire Construction.I could not be happier with my choice.The shutters are made very well and are powder-coated.The purchase included all of the required hardware which was powder-coated to match the shutters.The company is very customer-oriented.Michael and his staff were wonderful.They were attentive, helpful, and a delight to work with.The installation video on the website made the installation very easy.I highly recommend Empire Construction to anyone considering a purchase of hurricane shutters. Thanks again. Please say Hi to everyone,
