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.

Check the temperature after five to eight hours. If it is higher than 40 degrees, adjust the baffle knob to allow more cold air into your fridge and reduce the temperature. If it is lower than 38 degrees, turn the baffle knob the opposite way to restrict the flow of cold air from the freezer to the fridge. Once you've reached a range of 38 to 40 degrees F in your refrigerator, place the thermometer between packages of frozen food in your freezer, then wait five to eight hours. If the temperature is below 0 degrees F, turn the temperature knob up.
