Cyclone Debbie leaves shark in road

Poor shark. Beautiful animal. Cyclone Debbie reached category 4, which means catestropic damage and sustained 130 to 150 mph winds. One report says Debbie had winds up to 163 mph and is feared to have damaged the Great Barrier Reef. Sustained winds over 150 mph would make Debbie a category 5, the worst possible on the current scale. Human casualties are not yet known.

An Australian journalist covering flooding from Cyclone Debbie was shocked to come across a dead bull shark that was apparently swept up in the deluge.

WIN News reporter Philip Calder tells news.com.au that he was in the town of Ayr to shoot video of a flooded road and couldn’t believe he came across a shark in a puddle. He says the shark is “the talk of the town” and many locals have turned out to touch it. …

Cyclone Debbie knocked out power to thousands when it slammed ashore with winds up to 260 kilometers (160 miles) an hour Tuesday.


What is the difference between a cyclone, a typhoon and a hurricane? Same thing, different names.

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.


Here’s the path Debbie took. While cyclones are normal in the area, climate change is believed to be increasing the frequency of the most severe cyclones. 

Severe Tropical Cyclone Debbie in 2017 was the strongest tropical cyclone in the Australian region since Cyclone Quang in 2015, and was branded the most dangerous cyclone to impact Queensland since Cyclone Yasi in 2011

This graph shows cyclone strength over 135 years, up to 2015.


Accumulated cyclone energy is a measure used by the National Oceanic and Atmospheric Administration to express the activity of individual tropical cyclones and entire tropical cyclone seasons, particularly the North Atlantic hurricane season. It uses an approximation of the wind energy used by a tropical system over its lifetime and is calculated every six-hour period.

The Accumulated Cyclone Energy  (ACE) doesn’t reflect destructive potential as well as Integrated Kinetic Energy (IKE). Here’s a graph of both compared, up to 2012.

ACE focuses upon the most intense winds concentrated in a storm’s center. Whereas, the actual destructive power of a storm depends upon the total area impacted with damaging winds, waves, and storm surge. The metric Integrated Kinetic Energy (IKE), developed in 2007, more accurately reflects the destructive potential. 



Catastrophic Damage will occur

Category 4 hurricanes tend to produce more extensive curtainwall failures, with some complete structural failure on small residences. Heavy, irreparable damage and near complete destruction of gas station canopies and other wide span overhang type structures are common. Mobile and manufactured homes are often flattened. Most trees, except for the heartiest, are uprooted or snapped, isolating many areas. These storms cause extensive beach erosion, while terrain may be flooded far inland. Total and long-lived electrical and water losses are to be expected, possibly for many weeks.

So far, the worst hurricane to hit the US was in 1900. It killed between 8,000 to 12,000 people in Texas.

The 1900 Galveston hurricane, the deadliest natural disaster to hit the United States, peaked at an intensity that corresponds to a modern-day Category 4 storm. 


For perspective, Hurricane Katrina of 2005, was the third-deadliest hurricane in United States history. It killed at least 1500 people.

Did you know that there are concrete hurricane proof homes? Might not be a bad idea, depending on where you live. 

ForeverHome is a total precast concrete home that is engineered to withstand hurricane-force winds. Everything is precast—everything. The foundation and floor system are cast on site, while the interior and exterior walls and roof are done in the factory. Everything is then assembled on site. “Innovation is present in virtually every feature of the construction, beginning with cutting-edge production processes and throughout the individual construction elements and their interconnection,” says Clinton Krell, an engineer on the project.


Reminds me of a story about three little pigs.
