Welcome to National Hurricane Preparedness Week
Call me crazy but I love severe weather, it totally fascinates me. I have fond memories of watching the nightly news with my dad and tracking the path of the hurricanes that entered the Gulf of Mexico. We had a giant fold out map that some mysterious organization would pass out at the doors of the local grocery stores. It took geography to a whole new level!
If you have noticed, I get excited about natural disasters. So allow me to share my enthusiasm for these fantastic and dangerous weather superstars.
What is a hurricane?
The politically correct term is “Tropical cyclone” – hurricanes and typhoons are regional terms. Simply put it’s a storm at sea, A BAD STORM at sea. According to the National Hurricane Center
“A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originate over tropical or subtropical waters and has a closed low-level circulation. Tropical cyclones rotate counterclockwise in the Northern Hemisphere.”
These storms have a progression of names as they advance in severity. Just like humans – infant, toddler, preschooler, kid, teens, adults.
Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less.
Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots).
Hurricane: A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher. In the western North Pacific, hurricanes are called typhoons; similar storms in the Indian Ocean and South Pacific Ocean are called cyclones.
Major Hurricane: A tropical cyclone with maximum sustained winds of 111 mph (96 knots) or higher, corresponding to a Category 3, 4 or 5 on the Saffir-Simpson Hurricane Wind Scale.
Hurricanes have their own Richter scale in a sense. Each category on the Saffir-Simpson hurricane wind scale has a corresponding expectation of damage on impact.
See NOAA for more ranking and damage information
A storm receives a name once is becomes a tropical storm. Names are from a predetermined set of lists (not one you would want to use for naming your children). If a hurricane is particularly destructive its name will be removed from the list. Curious about the 2015 hurricane names? Here’s a list of both Atlantic & Pacific storm names.
Common Hurricane hazards include storm surges, heavy rainfall, flooding, high winds, rip currents. It’s the combination of these hazards mixed with the rotation of the storm that gives these storms their potential for prolonged destruction.
Heed the Warnings
Just like in driving a car it’s important to understand what the signs mean and how to act accordingly. Meteorologists have numerous warnings, watches, and alerts making it a little confusing since they all seem pretty similar. Allow me to translate:
Watch = favorable conditions for a tropical storm or hurricane. “Be on guard!”. A watch tells you to prepare for action (see our next post for how to prepare for a hurricane). A watch is issued 48 hours in advance for outdoor preparations to happen, be diligent about staying informed. Don’t underestimate a tropical storm; they can still cause significant damage.
Warning = Take immediate action! A hurricane or tropical storm is imminent, occurring, or definitely coming your way. A Tropical Storm or Hurricane Warning is given for the areas the storm is expected to hit. Just because you may be outside the warning area doesn’t mean you won’t be impacted or shouldn’t take precaution.
Extreme wind warning – these are issued an 1 hour before hitting the eye wall (just before the eye of the storm) which usually has sustained winds of 115 mph or higher.
Other watches regarding flooding, tornadoes or other hazards will be issued with detailed information.
Tracking a Hurricane
T
ime to bust out your inner geek! Like I mentioned earlier this is one of my favorite parts of hurricane season. This is also a great opportunity for some fabulous family science and history lessons since you can track famous old storms just like the live ones. It’s easy to do.
Here is a great YouTube tutorial on tracking Hurricanes and links to blank maps for the Pacific and Atlantic oceans. Be sure you visit The Weather Channel for hurricane updates throughout the season and talk with your kids about making a family emergency hurricane preparedness plan. Happy Tracking!
Tyra Baird from Oregon simply lives a lifestyle of preparedness and has a passion for sharing it. She received a Bachelors from BYU-Idaho in Child and family studies, and Home and family living. As a stay at home mom of 6 children under the age of 10, she considers herself an expert in man-made disasters and daily coping. Emergency preparedness and self reliance has been a way of life since she was a child (her mom was in the Teton Dam flood as a teen and her dad’s just paranoid). Tyra and her husband have embraced preparedness wholeheartedly. She’s been in a tornado, tropical storm, flooding, snowed in twice, severe storms, and slept through a few minor earthquakes. All of them were pretty mild. Tyra is a self proclaimed nerd who simply enjoys reading, researching, writing, teaching, and public speaking.
I wish people had this article before hurricane mathew just blew right thru us. He did some serious work on my town and the coast! But we’re getting back on our feet unbelievably fast!
