Isohyets are used to show and predict rainfall totals in a certain area. An isohyet can be utilized to predict annual rain totals for a targeted location, or it can show actual recorded rainfall totals of an area following a storm much like the isohyet pictured above. The various levels of percipitation are represented by contour lines which differ in color to show the different rainfall amounts around a certain area. The map above concentrates of South Florida after Tropical Storm Leslie hit the region. The map key on the left shows that the contour lines represent rainfall totals in 2 inch increments, with a maximum rainfall amount be 17.50 inches recorded in South Miami, Florida. When dealing with isohyets the main focus is on rainfall totals, as well as predictions for general areas.
