Hurricane Irma Update Southern Florida Feeling the Wrath

Hurricane Irma began pounding southern Florida on Saturday afternoon.

The Atlantic’s strongest storm has left destruction across the Caribbean.

Emergency officials warned of 15ft storm surges and tornadoes and told those who have so far ignored evacuation orders: ‘You’re on your own!’

While the hurricane’s eye will not directly hit mainland US until Monday, its outer bands have already begun pounding parts of Miami and southeast Florida.

Two tornadoes hit Broward County after the National Weather Service issued a tornado watch on Saturday afternoon.

There is also a deadly threat of 15ft storm surges with residents being urged not to return home given the enormous outer bands.

6.3million people have been told to evacuate in anticipation of Irma and there are 70,000 people in evacuation shelters across Florida.

The state said Saturday that more than 400 shelters are open, mostly in schools, churches and community centers. The storm is set to move up the southwest coast, hitting Tampa on Monday.

Southwest Florida could see a storm surge of 15 feet above ground level, and entire neighborhoods stretching northward from Naples to Tampa Bay could be submerged.

About Hurricanes:

Hurricanes are the most violent storms on Earth. People call these storms by other names, such as typhoons or cyclones, depending on where they occur. The scientific term for all these storms is tropical cyclone. Only tropical cyclones that form over the Atlantic Ocean or eastern Pacific Ocean are called “hurricanes.”

Whatever they are called, tropical cyclones all form the same way.

Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface. Another way to say the same thing is that the warm air rises, causing an area of lower air pressure below.

A cumulonimbus cloud. A tropical cyclone has so many of these, they form huge, circular bands.

Air from surrounding areas with higher air pressure pushes in to the low pressure area. Then that “new” air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean’s heat and water evaporating from the surface.

Storms that form north of the equator spin counterclockwise. Storms south of the equator spin clockwise. This difference is because of Earth’s rotation on its axis.

As the storm system rotates faster and faster, an eye forms in the center. It is very calm and clear in the eye, with very low air pressure. Higher pressure air from above flows down into the eye. Read more here
