Japan is in tropical area?

Hurricane Gustav is closing New Orleans and New Orleans Mayor Ray Nagin ordered a mandatory evacuation of the city. It is said that Gustav might become bigger than Katrina.

One resident says that hurricane comes every year, but it getting bigger year after year.

Recently terrible heavy rain attacks all around Japan, and it is called "guerilla heavy rain."

In Tokyo, it's been raining for the last a week. It's like rainy season seemingly but type of rain is a bit strange.

It's torrential heavy rain in a short time. Such type of rain happens all around Japan recently
After short torrential rain, the sun comes up, then soon it starts rain terribly. It's like the climate of the Tropics. It must be due to global warming. Japan will be included into tropical area sometime.

By the way, I don't think it good idea that the US names hurricanes human names. Hurricanes usually cause huge damage. For example hurricane Katrina, all people whose name is Katrina must feel bad.
