Washington, Sep 29 (TIWN) "Extremely dangerous" Ian made landfall as a Category 4 hurricane in southwestern Florida, according to the National Hurricane Center (NHC).

Dramatic television footage showed churning water submerging roads and sweeping away cars as the hurricane pounded the coastal city of Naples to the south of Fort Myers.  The NHC said Ian was packing maximum sustained winds of 150 miles per hour (240 kilometers per hour) when it made landfall and was already "causing catastrophic storm surge, winds and flooding in the Florida peninsula."  Ian is expected to affect several million people across Florida and in the southeastern states of Georgia and South Carolina and may have already claimed its first casualties.  The US Border Patrol said 20 migrants were missing after their boat sank. Four Cubans who survived swam to shore in the Florida Keys and three were rescued at sea by the coast guard.  As hurricane conditions spread, forecasters warned of a looming once-in-a-generation calamity.  "This is going to be a storm we talk about for many years to come," said National Weather Service director Ken Graham. "It's a historic event."  Punta Gorda, north of Fort Myers, was being pounded by torrential rain and streets emptied as the howling winds ripped fronds off of palm trees and shook electricity poles.
