Editorial note: Hurricane Matthew, which has already left it’s devastating mark on Haiti is set to be the first category 5 Hurricane to hit since 2007 and is set to hit the US coast on Friday morning and could make landfall.

It is hard to pull one’s eyes away from the images of Haiti in the aftermath of Hurricane Matthew. If one needed proof that we live in an indifferent universe, that broken land and its suffering people caught in a new, unfolding catastrophe should suffice.
Hurricanes are getting increasingly destructive
Through the fog of presidential politics that has enveloped the media, news of this storm is beginning to reach people and disrupt lives and plans. I for one was at the airport, ready to board a flight to Florida to participate in a climate conference when I received the news that the conference was likely going to be cancelled, and that I should not travel. This is how fast this storm developed.
Matthew turned from a tropical storm into a Category 5 hurricane in just 36 hours, mainly fueled by warmer than average waters. According to Climate Signals, as of October 3, Matthew was the longest-lived Category 4-5 hurricane and had generated the most Accumulated Cyclone Energy (orACE, a measurement that expresses the activity and destructive potential of individual tropical cyclones and entire tropical cyclone seasons) in the eastern Caribbean of any Atlantic hurricane on record.

Impacts of disasters fall disproportionately on the world’s poor and vulnerable communities
This is particularly true of disasters with climate connections.
Matthew may end up dumping as much as 40 inches of rain in Haiti and the Dominican Republic, whipping the country with sustained winds of 145 mph (the average annual rainfall in Port-au-Prince is 33.68 inches). Already reports are coming in of the devastation it is bringing to those nations.
The impacts from Matthew will be felt by wealthy and poor communities alike, but the latter usually are not well prepared and lack the resources to rebound and get back on their feet in a timely or comprehensive manner. And this is not true only of foreign nations: many communities along the US coast find themselves in the same situation.
Florida has a whole generation of people who have not witnessed a major hurricane
Such a powerful hurricane brings rain and storm surge that can be life-threatening, as we have already seen in Haiti. With each recent update, the track of the now Category 4 hurricane has moved farther west, and closer to the US East Coast.
Right now, Matthew is on track to skim very close to the Florida coast from late Thursday, October 6 through Friday, October 7. By Saturday, October 8, the storm will begin impacting Georgia and the Carolinas. In the Southeast, some evacuation orders have already been issued.
This is a gravely serious storm, the likes of which states like Florida have not seen in a generation. Indeed, since Hurricane Andrew, in 1992, millions of people have taken up residence along the Florida coast.
Most of today’s East Coast residents have never experienced a hurricane of this magnitude and power, nor much considered the risks. And they now have a matter of hours to prepare.
Here I will focus on what we need to know to weather this storm. In subsequent posts, we will address what can be learned in its aftermath.

Preparedness is essential and must be taken seriously
A storm moving along the Atlantic can have a variety of impacts. Such a powerful hurricane brings rain and storm surge that can be life-threatening. For Matthew, the most up-to-date predictions are:
Storm surge will build as the hurricane approaches land and drives water ashore. Forecasts are still preliminary given the uncertainty of the precise storm track but suggest that coastal areas in Florida, Georgia, and the Carolinas will see flooding greater than 1 foot and greater than 3 feet in some places. Check here for the latest updates and forecasts.
For those beginning to wonder what this storm may mean for them, UCS has compiled a set of resources not only for the US but for the other affected nations:
Matthew reminds us, however, that we need to continue to talk about climate, and not only our country’s disaster policy shortcomings but also (and importantly) the impacts of on the world’s poor and vulnerable communities.
