Hurricane Irma: One of the most powerful Atlantic Ocean storms on record

On Tuesday 5th September, Hurricane Irma grew into one of the Atlantic's most powerful storms. The category 5 hurricane - highest category storm on the Saffir-Simpson scale (a commonly used scale that attempts to measure potential property damage from storm winds) - had wind speeds around 185 mph, matching those of Wilma in 2005 which killed 87 people, costing billions in damage. As it moved through the Caribbean and towards southern Florida, Irma sustained winds of 185 mph for 37 hrs, making it the longest on record any tropical cyclone around the world has maintained this intensity.

Hurricane Harvey causes catastrophic flooding in Texas

Hurricane Harvey bought “catastrophic” flooding to the US state of Texas at the end of August, in what could be the costliest storm in US history with damage estimated to be in the billions of dollars.  Harvey deposited the heaviest total rainfall from any tropical cyclone in the continental US in records dating back to 1950, topping the 48 inch storm total in Medina, Texas, from Tropical Storm Amelia in 1978.
