This storm has certainly strengthened very quickly: from a small depression to a Typhoon in 24 hours is fairly rapid. Looks like another storm bound for Japan as has been said. Here is the latest discussion:

So, Usagi is expected to intensify further under favourable conditions but should weaken before making landfall in Japan, exact location can't be certain yet but landfall in Japan itself is looking very likely.

hi mate was woundering if you could tell me, do they kind of storms cause much flooding. like what can happen in america? or are the flood defences stronger?

Hi Cookie, that's a difficult question as I don't know much about the topography of Japan. I know Super Typhoon Man-Yi caused landslides and flooding so flooding definately is an issue in these Japanese landfalling typhoons. Some parts of the south coast of the USA are very low lying (eg. New Orleans, with some parts 2 meters below sea level) which is why flooding was so catastrophic with Hurricane Katrina. So these typhoons do cause dangerous floods but perhaps not as bad as vunerable parts of the gulf coast of the USA.

EDIT: just worth saying that Usagi is nearing cat 3 strength on the saffir-simpson scale as it heads northwestwards towards Japan.

[Somerset Squall]

Typhoon Usagi is now cat 4 on the saffir-simpson scale and is very likely to become a Super Typhoon as more strengthening is anticipated. Perhaps category 5 isn't out of the equation.

Red Alert Country(s) or Province(s)

Japan

probability for CAT 1 or above is 75% in about 36 hours

probability for TS is 85% in about 36 hours

hopefully thier wont be any loss of life

[mezzacyclone]

Just seen it on Fox news, pretty intense @ 200kmh+ and still strengthening toward western Japan

shifting the focus away from the western? hemisphere somewhat eh!

[Cookie]

less then 12 hrs till its due to hit!

[Somerset Squall]

Certainly still very strong, but it is on a weakening trend now as expected nearing Japan due to cooler waters. Still a cat 3 though and I would expect it to make landfall at the higher end of a category 2 typhoon when it makes landfall tommorrow.

Latest remarks on the system:

REMARKS:

012100Z POSITION NEAR 29.6N 133.4E.

TYPHOON (TY) 05W (USAGI) LOCATED APPROXIMATELY 305 NM SOUTH-

EAST OF SASEBO, KYUSHU, HAS TRACKED NORTH-NORTHWESTWARD AT 17

KNOTS OVER THE PAST 06 HOURS. TY 05W HAS WEAKENED SLIGHTLY OVER

THE PAST 06 HOURS WITH DVORAK INTENSITY ESTIMATES RANGING FROM

102-115 KNOTS. ANIMATED SATELLITE IMAGERY AND A 011644Z AMSR-E

IMAGE DEPICT WARMING EYEWALL CLOUD TOP TEMPERATURES. THE TRACK

PHILOSOPHY HAS NOT CHANGED AND THE DYNAMIC AIDS ARE IN GOOD

AGREEMENT WITH THE TRACK, HOWEVER, THE INTENSITIES WERE LOWERED

AFTER TAU 24 DUE TO VERTICAL WIND SHEAR, LAND INTERACTION, AND

COOL SSTS OVER THE SEA OF JAPAN (< 24-25C). ADDITIONALLY, MODEL

ANALYSIS INDICATES THAT THE SYSTEM WILL BEGIN EXTRA-TROPICAL

TRANSITION (ET) AFTER TAU 24 AND WILL COMPLETE ET BEFORE TAU

72, PRIOR TO TRACKING OVER/NEAR MISAWA AS AN EXTRA-TROPICAL

SYSTEM OF 45-KNOT INTENSITY. MAXIMUM SIGNIFICANT WAVE HEIGHT

AT 011800Z IS 35 FEET. NEXT WARNINGS AT 020300Z, 020900Z,

021500Z AND 022100Z./

Should become extratropical soon after landfall then but will still be a fairly potent storm as it tracks across the whole of Japan, west to east. Lets hope that it won't be deadly and that expenses are minimal.

[Somerset Squall]

The typhoon made landfall yesterday as a category 2 and has now emerged over the Sea Of Japan, and will continue to track northeastwards whilst becoming extratropical. Thankfully, according to this report, deaths and damage have been fairly limited so far.
