Hurricane Florence is predicted to slam into the US East Coast as an "extremely risky major hurricane" overnight on Thursday.
"The crew of @Space_Station is thinking of those who will be affected", Arnold said in a tweet. "A few moments later, #Isaac & the outer bands of #Helene were also visible", Arnold tweeted, referring to two other hurricanes swirling to the east of Hurricane Florence. For the Carolinas, the NHC predicts a "life-threatening storm surge and rainfall".
Florence is now a powerful Category 3 storm with winds of 125mph, and is expected to strengthen before making landfall along the Carolina coast later this week. Since reliable record-keeping began more than 150 years ago, North Carolina has only been hit by one Category 4 hurricane: Hazel, with 210 km/h winds in 1954.
At the same time, NASA is tracking Hurricane Florence with the Suomi NPP satellite, which passed over the eye of the storm in the early hours of September 12, at 2:12 a.m. EDT.
