I suggest that weathermen concocted this story to try to appear as more than just poorly dressed comic relief for the news. Past attempts to be taken seriously have failed. But few people fell for that lame trick. Their newest plan is to make weather appear newsworthy, but the weathermen can't wait for another blizzard or hurricane. The weather isn't that unusual.
Weather is different every year.
Some years there are droughts in the Midwest, some years there are blizzards across the north, and some years the Bahamas doesn't even get hit by a hurricane, yet no water currents caused these incidents. The only reason this year has a goat to blame is because the weathermen arbitrarily decided to unveil their creation this year. No one can even observe their bluff, because the only people who care what is happening with water currents are in on the scheme. The jig is up, and Spite Magazine has called you on the ruse. Nice try, and better luck next time.
