Come Hull or High Water: One Hull Of A Hurricane Preparation Article

"If I owned Hull and Texas, I would live in Hull and rent out Texas."
Hull sticks way out into the ocean, which is never a good thing in a coastal flooding scenario. It is very low-lying in spots, also a bad. It is also very densely populated, which complicates things further.

That map above is a Hurricane Inundation Map, from FEMA, MEMA, NOAA and NHC. The analysis is by ME, a lowly NWS volunteer spotter who happens to be Boss Hogg here at Cranberry County Magazine. The map is based on the zany-weatherman-titled SLOSH model of storm surge inundation.

"Storm surge" is the water pushed onshore in a storm. If you're standing at the high tide mark and a ten foot storm surge comes ashore, you'll be under ten feet of water. You can call it a Deathflow or Liquid Doom if it gets your people moving more quickly.

These maps depict the estimated storm surge for Hull in the event of a direct-hit hurricane arriving at mean high tide. They also show what sort of storm would e required to flood certain areas. They do not depict freshwater inundation that could result from heavy rain, sewer backups, and river/stream overflow.

The maps work like this:

Light Green = Category 1 storm. The Halloween Gale is a good-although-offshore example of a Category 1 hurricane, while the Blizzard of '78, though not a hurricane, is also a good model for estimating this sort of damage/risk.

Dark Green = Category 2 hurricane. Hurricane Bob was a weak Category 2 hurricane. Yes, "weak" and "Category 2 hurricane" are funny words to string together.

Yellow = Category 3 hurricane. We have only had five Category 3 hurricanes since the Other Man arrived in 1620, the last one being Hurricane Carol in 1954.

Red = Category 4 storm. We've had one in recorded history, in 1635.

Flesh = 100 Year FEMA Flood Estimates. This is the "hundred year storm" you hear people speak of, although you have to go pre-Colombian to find evidence (marsh mud samples are analyzed for otherwise unexplainable sand layering to determine prehistoric hurricane histories for areas with dunes in front of marshes) of storms of this power striking New England. According to my research, we got tuned up on to this extent in the 1100s, the 1300s, and the 1400s.

As we were saying before, you people are in a Hull of a spot.
"We're surrounded!" "We're supposed to be surrounded, we're paratroopers Hull."
Yes, you are surrounded... by water, and you don't live on mountains. When the water rises, it likes to come and visit coastal communities. That is going to make things very sketchy in H-you-double hockey sticks.

Hull could go from peninsula to island very quickly if a hurricane came to town. These maps help give you an idea of what sort of risk you face.

Hull does catch a break, in that a hurricane is almost never going to land a direct hit on Hull. It will come ashore on the South Coast, Cape Cod or Rhode Island before reaching Hull, and that will blunt the effects somewhat.

Hull will also benefit from the fact that hurricanes historically have a tendency to right-hook just before hitting Cape Cod, thus keeping Chatham and Wellfleet between the hurricane and Hull. That effect is erased when the storm plows through Cape Cod Bay, of course.

You can analyze the map for yourself, although I do feel obliged to note that Hull High will be underwater in even minor storms. The roads out will be blocked as well.

Talk to old-timers who were on Hull for Hurricane Carol or even the 1938 hurricane. Locals know stuff that FEMA doesn't, as odd as that sounds. I disagree with FEMA on my own neighborhood (Duxbury Beach), and my hurricane pedigree only runs back to Hurricane Belle. Keepers of the Old School actually watched hurricanes hit Hull, something most FEMA kids can't say.

Hull does have some high ground (World's End is safe from most storms, I was somewhat disappointed to discover), and you should both 1) know where it is and 2) befriend people who live on it.

We can now move on to the Evacuation Map.

"Oh Baby, Please Don't Leave Me!"
This one is easier to read. Red means "They'd better leave," and Yellow means "You'd better leave, too."

Hull, in a hurricane, is a French word for "Flee." Pretty much everyone in town should give serious thought to a good Skedaddle. A good run is better than a bad stand. That water will be coming ashore angry.

You don't HAVE to go. However, the cop you read the Constitution to before the storm will also be the one who may have to pull you out of the floodwaters, so use your best discretion and stuff.

Hull will be a nightmare to evacuate. As anyone who drives home from a bar knows, there's really only one road out. Hull also enjoys the distinction of being the 4th smallest town by land area in the state, yet having one of the longer coastlines... while also being top 30 in population density.

Also note that you can be killed by a hurricane very far back from shore, even in areas not demarcated by either map. A river could overflow, power lines could fall, the winds could decapitate you with a pizza box, and you could very easily end up in a sharknado.

We want you alive. We want you alive for monetary reasons, as this site depends on you dropping by now and then. We want you alive for reasons of professional pride, i.e. "If they listened to me, they got out in time." We also want you alive for regular, nice-people reasons.

"I advocate hanging on as long as possible."
