An eerie communications blackout accompanied Hurricane Dorian’s excruciatingly slow, 48-hour passage across the Bahamas early last week. Satellite images of the category 5 storm – as seen in last week’s Eyewitness spread – merely hinted at the carnage taking place beneath. With the storm’s passing late last week the devastation was laid bare: hundreds of people missing and an estimated 70,000 left homeless.
