​Just moments ago the National Hurricane Center updated their X, formerly known as Twitter, with the following message:

"5am EDT 30 Aug: #Idalia has become an extremely dangerous Category 4 hurricane, and is nearing landfall in Florida Big Bend region this morning. Catastrophic & life-threatening impacts from Storm Surge & Winds expected as Idalia moves ashore."

The post is accompanied by a screenshot of "Key Messages for Hurricane Idalia" that includes information on the catastrophic impacts the storm could bring ahead of its landfall.

While areas of Florida have already been experiencing storm surges and high winds, according to the NHC, damaging winds and flooding are now expected as far north as Georgia and South Carolina.

​What is a Category 4 Hurricane?

A category 4 hurricane is a powerful storm characterized by sustained wind speeds between 130 and 156 miles per hour (or 209 to 251 kilometers per hour). It falls under the highest category on the Saffir-Simpson Hurricane Wind Scale. Here are some key characteristics of a category 4 hurricane:

1. Wind Speed: Category 4 hurricanes have extremely strong winds that can cause significant damage to buildings, trees, and infrastructure.

2. Storm Surge: They generate an extremely dangerous storm surge, with ocean waters often rising 13 to 18 feet (or 4 to 5.5 meters) above normal levels. This surge can result in extensive coastal flooding.

3. Damage Potential: Category 4 hurricanes can cause severe structural damage, including the potential for complete roof failure on many residences and industrial buildings. They can also uproot large trees and cause widespread power outages.

4. Impact: The impacts of a category 4 hurricane extend well inland, causing flooding, high winds, and destruction along its path.

5. Preparedness: As category 4 hurricanes are extremely dangerous, preparedness measures such as evacuation orders, securing property, and stocking up on essential supplies are strongly advised.

It is important to stay informed through official sources like the National Hurricane Center and follow any guidance or warnings issued by local authorities when dealing with a category 4 hurricane.
