Everyone is talking about Harvey, Irma, Jose and Katia.

They are the names of very large storms, affecting the area around the Caribbean*, Mexico and the southern United States.

Hurricanes are given names, like “Irma” to make it easier to refer to them.

People in these areas are used to dealing with storms. But these storms are much larger than normal. They have very high winds—up to 120 kilometres an hour—with lots of rain that can flood people’s houses and force them to leave the area. (In this case, leaving your home is known as “evacuating.”) In Florida, more than 6.4 million people have been told to evacuate before Irma gets there, according to a report from CBC News.
