Wind speeds are in knots and temperatures are in degrees Fahrenheit.

Note: 1 "knot" means 1 nautical mile per hour and is about 1.15 miles per hour. A nautical mile is one-sixtieth (1/60) of a degree of latitude on a great circle. A nautical mile is used in aviation and marine navigation. A nautical mile is about 6076 feet.
