Flooding Around the World: Florence, Mangkhut and Helene

Three storms have been dominating the news and weather reports over the weekend. Hurricane Florence made landfall in North Carolina on Friday, Typhoon Mangkhut left a trail of destruction across the Philippines on its way to Hong Kong and China and the remnants of Hurricane Helene is due to bring wind gusts of up to 80mph to British shores overnight. We thought we’d take a look at the how these storms are causing flooding events and how the impact of climate change is making storms more dangerous and more frequent.

Hurricane Florence

Coastal residents of the Carolinas were given plenty of warning to evacuate the path of Hurricane Florence. But a few people determined to stay and some paid for that choice with their lives. Like last year’s Hurricane Harvey, Florence slowed down as she approached the coast, but this had the affect of acting like a giant pump transferring moisture from the sea to the land. The storm surge combined with the rainfall meant that rivers and drainage systems far inland are still being overwhelmed. The effects likely to be felt for some time yet as the water that falls in the uplands makes its way to the already swamped basins.

Typhoon Mangkhut

The strongest storm the world has seen so far this year has likely caused hundreds of deaths and millions of people to be displaced. 

Ex-Hurricane Helene

It is unlikely that Ex-Hurricane Helene is making the news in other parts of the world. The storm dissipated most of its energy while still out in the unpopulated parts of the Atlantic. However, its remnants are headed our way and strong gusts of wind can lead to localised flooding in coastal communities.

The Impact of Climate Change

Climate change is causing the oceans to warm up. Hurricanes are created by energy transferring from the warm ocean to cooler air above in line with the principles of thermodynamics. As the intensity and frequency of hurricanes increase, so to does the likelihood of them spinning off and affecting countries, such as the UK, whose northerly latitude has historically meant that we escaped their worst effects.

Flood Ark Flood Barriers

Our flood barriers have undergone extensive hurricane resistance testing by the American Test Lab Inc – an independent firm that tests the suitability of products for deployment in a High Velocity Hurricane Zone. Our bespoke flood barriers are compliant with FBC TAS 201, 202, 203 (Florida Building Code – Testing Application Standards) qualifying Miami-Dade County and ASTM E 1886, E 1996-97 / 02, 330-02 (American Society for Testing Materials).
