Observe animals. They are more likely to react to changes in air pressure than we are.
* If birds are flying high in the sky, there will probably be fair weather. (Falling air pressure caused by an imminent storm causes discomfort in birds' ears, so they fly low to alleviate it. Large numbers of birds roosting on power lines indicates swiftly falling air pressure.)
* Seagulls tend to stop flying and take refuge at the coast if a storm is coming.
* Animals, especially birds, get quiet immediately before it rains.
* Cows will typically lie down before a thunderstorm. They also tend to stay close together if bad weather's on the way.
* Ants build their hills with very steep sides just before a rain.
* Cats tend to clean behind their ears before a rain.
* Turtles often search for higher ground when a large amount of rain is expected. You will often see them in the road during this period (1 to 2 days before the rain).
