In this article, we'll find out what causes rip currents, how you can recognize them and what you should do if one takes you out to sea. A rip current is a narrow, powerful current of water running perpendicular to the beach, out into the ocean. These currents may extend 200 to 2,500 feet (61 to 762 m) lengthwise, but they are typically less than 30 feet (9 m) wide. Rip currents can move at a pretty good speed, often 5 miles per hour (8 kph) or faster.

Okay, maybe not the most elegant Christmas gift, but a refrigerator thermometer is a terrific idea. Your gift giver has my admiration. Hereâs the short answer: The ideal refrigerator temperature, measured in the middle of the middle shelf, is between 35 and 38 degrees. Your fridge needs to be warm enough so your food doesnât freeze (32 degrees) but not so warm that it crosses into the bacterial danger zone (above 40 degrees). So a number somewhere around the middle of those two bookends makes sense. You probably know that some places in the refrigerator are warmer than others.
