The stewing heat and humidity of a young summer finally gave way to the first tropical cyclone to threaten the United States this year. Tropical Storm Cindy is gathering steam in the Gulf of Mexico this week, and it promises to bring heavy rains to just about everyone in the southeastern United States. It won’t be a strong storm when it makes landfall, but wind isn’t as much of a concern as the copious amounts of tropical moisture being dragged northward, culminating in lots of precipitation and the potential for flooding.

As of Wednesday, June 21, 2017, tropical storm warnings are in effect for parts of the Gulf Coast from areas west of Houston, Texas, to as far east as Pensacola, Florida. Tropical Storm Cindy had winds up to 60 mph at 8:00 a.m. EDT Wednesday morning, and forecasters expect the storm to maintain winds of around 50 mph as it nears landfall. Winds of 45 mph are what you'd see in a healthy thunderstorm, but constant blustery winds over wet soil will make it easier for trees and power lines to topple over.

The traditional hurricane forecasting map—showing the forecast track of the center of the storm with a cone of uncertainty sweeping along its expected path—doesn't do much good in this situation. Sure, some areas will see gusty winds and power outages, but the real story with Tropical Storm Cindy is its rain. Cindy is a lopsided tropical storm with almost all of its heavy rain and wind shoved off to the east of the low-pressure center by wind shear higher up in the atmosphere. That's common to see in a weak, early season storm like this. Cindy's heavy rain will extend far beyond the center of the storm due to its lopsidedness and large size, so the forecast tracks we're all used to seeing don't go far enough to cover the threat posed by this storm. (If you'd like to see for yourself, forecasts are always available on the National Hurricane Center's website.)

Tropical Storm Cindy will produce rainfall totals in the double digits in some locations through the end of the week, and the moisture from its remnants will continue to track inland through the weekend. The Tuesday morning precipitation forecast from NOAA’s Weather Prediction Center called for a widespread area across the Southeast to see more than three inches of rain by the time the storm finally clears out of the picture at the end of the week. Moisture from a landfalling tropical system is usually bad enough, but this storm will run into a pesky stationary front draped across inland areas of the Southeast. This front will help wring out the moisture and make it rain harder and longer than it would have otherwise.

This much rain over a short period of time will lead to widespread flooding concerns. If you live in or are visiting affected areas, make sure you know more than one route to get to where you're going. More than half of all deaths in a tropical storm or hurricane are caused by drowning. It's impossible to tell how deep the water is on a road before you drive across it, and it takes a surprisingly small amount of moving water to lift a car and sweep it downstream.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

7 Facts About the Hurricane Highway

Autumn is the peak of hurricane season, also known as Cape Verde season, after the islands where the so-called "hurricane highway" originates. Here are seven facts about this awesome—and sometimes deadly—weather phenomenon.

1. The hurricane highway begins near the African coast.

The Cape Verde Islands, located off the northwest coast of Africa, are where the hurricane highway starts. Thunderstorms destined to become hurricanes often form into a tropical depression near the islands, slowly organizing and strengthening over the following week as the system moves toward the Caribbean. These storms have a long time to get their act together, but they also have to cover a lot of distance without losing their power to reach the East Coast as a hurricane. Some storms are able to thrive with little wind shear, ample warm water, and moist air, while others starve and dissipate if they encounter cooler waters and strong winds, or ingest dry, dusty air blowing off the Sahara Desert.

2. An easterly jet stream gives rise to the hurricane highway.

It’s hard to imagine from North America that a couple of thunderstorms on another continent thousands of miles away can swirl up into a monstrous storm, but it happens almost every year. The extreme temperature gradient between the blistering heat of the Sahara Desert and the more temperate climate of the savanna to its south creates an easterly jet stream that triggers clusters of showers and thunderstorms. These clouds then move from east to west, emerging off the western African coast near the Cape Verde Islands. Every year, the right conditions turn a handful of these localized storms into tropical storms that make their way across the Atlantic.

3. The biggest hurricanes start with the smallest storms on the hurricane highway.

Hurricanes, cyclones, typhoons—these are all names for the same force of nature, like Hurricane Andrew, which hit the East Coast in 1992. Cyclones like Andrew don’t just form out of thin air. All tropical cyclones require a relatively tiny “nucleus” of thunderstorms in order to develop. When the air and water temperatures are right, these groups of thunderstorms sometimes spin up into a fierce low-pressure system capable of causing a lot of damage. We see lots of these seedling thunderstorms over the ocean every year, but only a small number of them become hurricanes.

4. Hurricanes form in different places in different months.

Where a tropical storm or hurricane begins its trip across the ocean depends on what time of the year it forms. Storms that form early in the season usually get their start from thunderstorms or cold fronts that stall over the water very close to land; almost all of the storms that form in the Atlantic in June come to life within a few hundred miles of land. When we reach the peak of hurricane season, though, they start to form farther and farther out in the ocean—all the way out to the shores of Africa.

5. Fall is the peak of hurricane season on the hurricane highway.

Hurricane season in the Atlantic Ocean runs from June 1 through November 30. Storms are most common during that six-month stretch of the year, but sometimes they can form earlier or later too. That said, the period between the middle of August and the middle of October is typically the climatological peak of the season. That’s because, as the ocean water gets warmer, the atmosphere becomes conducive to vigorous storms, increasing the risk for hurricanes and tropical storms.

6. Cape Verde hurricanes can easily land in the record books.

Tropical waves traveling west from the coast of Africa in the middle of the summer are the culprits behind some of the worst hurricanes we’ve experienced in the United States. For example, on August 8, 2005, a small tropical wave emerged off the coast of Africa, soon becoming Tropical Depression 10. That depression would fall apart a few days later, but its remnants kept moving toward the U.S., redeveloping into a new tropical depression over the Bahamas on August 23. That new tropical depression became Hurricane Katrina, the costliest hurricane to ever strike the United States.

It’s a similar story for many—but not all—major hurricanes in recent history. Hurricanes Andrew, Dennis, Ivan, Isabel, and Ike were all Cape Verde–type storms that sprang to life thousands of miles away from where they would ultimately wreak havoc.

7. Strong hurricanes can still form in other places in autumn.

While the far eastern part of the Atlantic Ocean is a hotbed of activity this time of the year, it’s not the only place you need to watch if you live near the coast. Storms that form close to land can quickly spin themselves into catastrophe. Hurricane Sandy formed just south of Jamaica and hit New Jersey in a matter of days in 2012. A tropical depression that developed east of Florida on September 18, 2005, exploded into Hurricane Rita just three days later, with 180 mph winds—the most intense storm ever recorded in the Gulf of Mexico.

Meteorologists are currently predicting an above-average hurricane season in 2020. It may be worth preparing: NOAA suggests gathering a few key disaster supplies to have on hand, getting an insurance check-up, and locating the safest high ground.
