Lightning, thunder, floods, landslides..plan accordingly
Patmos in the archipelago of the Dodecanese is sometimes called the "Jerusalem of the Aegean" because it is the island where John the Apostle wrote the Book of Revelation, the final book of the New Testament. This makes it a magnet for the Christian faithful and usually the well-heeled place is pretty calm. No airport. Nice beaches. Pricey properties. But for the next six months, a state of emergency.
Winter storms pummeled the island, Greek newspaper Protothema reported, causing widespread flooding and landslides. A state of emergency is in effect for six months as regional authorities assess the damages. If you're planning on visiting this part of Greece my recommendation is to move your timeline to the beginning of July, maybe the latter half of June.
