A hurricane's eye can be deadly and calm at the same time. Most hurricanes will move on to a new place if they haven't lost momentum. Before exploring this scenario, here are some general questions and information about hurricanes:

Structure of Hurricanes

Hurricanes, potent natural storms, unleash formidable power through strong winds, storm surge floods, heavy rainfall causing inland flooding, tornadoes, and rip currents. Their unique structure enables this havoc.

As storms evolve into hurricanes, surface winds spiral in a continuous circular motion. Meteorologists label this "closed circulation." The circulation direction depends on the storm's location: counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

These swirling winds give rise to the hurricane's defining feature-the tranquil, clear "eye." Encircling it is the ferocious eyewall, where the strongest winds reside.

What is the Eye of a Hurricane?

The eye of a storm is a circular zone with winds of up to 15 miles per hour, weaker than the storm's main winds. It's enclosed by the eyewall, a ring of cumulonimbus clouds, typically 20 to 40 miles in diameter, although it can reach up to 120 miles. Inside the eye, there's calm weather, sometimes even sunshine. When a region is in the eye, the hurricane is only halfway through.

A hurricane's eyewall forms at 74 mph, creating a ring of intense convection around the calm eye. It houses the strongest surface winds due to an updraft from sinking air in the eye. The eye has the lowest surface pressure and warmest temperatures aloft in the storm.

What Happens When This Calm Yet Deadly Part Passes?

In the eye of the storm, many forget that it means only half the hurricane has traversed the area. The rear of the hurricane is equally perilous, potentially more so if it connects to the sea. A less-known hazard is the eyewall replacement cycle, where the eye's diameter spontaneously alters, posing severe risks. At peak intensity, the eye can shrink due to pressure, weakening the eyewall and unleashing powerful winds.

Even in the apparent calm of the eye, heed expert advice, and stay indoors. The area remains in potential danger. Shelter should be maintained until receiving an official clearance that the hurricane has passed.

After The Hurricane

When the hurricane's eye passes, there's a temporary wind lull, but hazards persist post-storm. Officials advise locals to stay clear of damaged areas. After the eye, expect winds from the opposite direction, possibly stronger. Stay informed through NOAA Weather Radio or local news.

Return home only when officials deem it safe. Drive sparingly, avoiding flooded roads, fallen objects, and damaged infrastructure. Check your property for hazards like loose power lines, gas leaks, and structural damage. Avoid buildings with gas odors, floodwaters, fire damage, or lacking official clearance.

Carbon monoxide poisoning is a post-storm danger; never use generators indoors. Opt for battery-powered flashlights over candles, as sparks can ignite gas leaks. Safety is paramount as you navigate the aftermath of a hurricane, protecting yourself and your community from hidden threats.
