Weather Maps

Weather maps help us see what the weather is doing over a large area. They show temperature, air pressure, wind, and rain using special symbols and colors. Meteorologists use weather maps to track storms and make forecasts. You can see weather maps on TV, in newspapers, and online.

Reading a Weather Map

Weather maps use symbols to show different conditions. A big red L means low pressure, which often brings rain. A big blue H means high pressure, which usually means clear skies. Blue lines with triangles show cold fronts. Red lines with half circles show warm fronts. Colors on the map often show temperature zones.

How Weather Maps Help

Weather maps help people prepare for what is coming. Farmers check maps to decide when to plant or harvest. Pilots use them to plan safe flights. Emergency teams watch for severe weather warnings on maps. By looking at how weather patterns move, forecasters can predict what the weather will be like tomorrow.
