Hurricane update - 29 July

Looks like Typhoon Usagi is going to make headlines for all the wrong reasons. Only a tropical storm north of Guam at present, this system will balloon into a typhoon with winds of 110 knots / 125 mph by the time it strikes mainland Japan near Kyoto on Friday. A fairly big margin for errors at this stage, but things are not looking good.

Another cyclone might develop in the southern hemisphere, west of Sumatra in the Indian Ocean. Quite unusual to have a cyclone in what is the southern hemisphere winter, but if the water is warm enough and the atmospheric conditions sufficiently conducive, it can happen. No land threatened at this stage.
