Dianmu Advisories

[SupertyphoonTip]

It isn't historic, but it is unusual. Going back to 1974 (30 years), out of 491 typhoons, 21 were 150 knots or higher at maximum wind speed, the last one being Maemi last year. However, since 1974, only 2 150-knot supertyphoons have developed before July. These were in 1986 and 2000. Now, Supertyphoon Dianmu is added to that list.

Here's an update for Dianmu.

15.1N 136.0E
180 mph (155 kt)
879 mb (25.96")

Now that is 1 mean storm..

Do you think this will get any stronger???

AllI can say is WOW! I am sure glad these storms don't develop in this area.

Ditto that. Though it would be cool, I would never want a storm like that bearing down on me!

[Steve H.]

Remember though, there was David and Allen and Mitch, the last having sustained winds of 180 mph with gusts over 200. It can happen, but conditions have to be ideal.

[SupertyphoonTip]

Looks like the winds have peaked...weakening should begin soon and hopefully Dianmu won't be very strong as it makes landfall in Japan on Monday morning.

These storms can and will develop in the Atlantic basin from time to time--usually in the Western Caribbean or the gulf of Mexico if the conditions are just right. Hurricane Gilbert and Mitch being good examples of storms every bit as large and powerful as Western Pacific Super Typhoons. And, of course, Camille and the Labor Day 1935 Hurricane, though more compact, were also just as intense. Considering pressure differences between the Atlantic and the Pacific, when Atlantic basin hurricanes maintain pressures below 915 mb for a day or more, their wind speeds will be right up there with the strongest the Western Pacific has to offer. It is astonishing to think that Gilbert's wind speeds may have not even had enough time to top out prior to landfall over the Yucatan because typically an Atlantic storm with sub 900 mb readings, given enough time for the centripetal wind forces to catch up, should be over 200 miles per hour sustained. What ifs being considered, imagine if Gilbert had taken on a more NW component and moved through the strait into the central Gulf of Mexico. In avoiding the Yucatan landmass, Gilbert would have had a frightening chance to maintain a pressure around 900 mb until a coastal landfall in the States. There will be a monster hurricane in the Gulf again some day, it is only a matter of atmospheric conditions and timing.

Is beautiful to see these monsters pop up from time to time, or from year to year, but is always wonderful to see them stay away as far as possible from any landmass. One of these monsters can make a weak country economy go really downhill, and the deaths are counted always by the thousands.

Over there they get all the good stuff Looks like there could be gusts to 190mph.

I thnk they don't have the same opinion, for example, I don't think the people in the Philippines like to have 2 or 3 tropical systems hitting them every month.

[Janie34]

A classic super typhoon. Nice piccies!

That is nothing to laugh about when that kind of monster with winds above 180 mph goes to any place in the world.

Updating the tropics today shows several things going on. The lead story is supertyphoon Dianmu, which has most likely peaked in intensity at this particular hour after a period of very rapid deepening. Meanwhile the Gulf Of Mexico is quiet, however tropical moisture continues to advect north from the Gulf ahead of an upper level disturbance centered over the eastern art of Texas. The biggest threat with this upper low is heavy rain. However there was a tornado warning issued around 7 AM CDT for the Galveston County area including League City, TX. This was most likely a rain wrapped tornado and was doppler radar indicated. As a result, any storms could produce an isolated tornado spinup from eastern Texas and Louisiana northward through Arkansas, western Tennessee, and western Kentucky as well. However with respect to tropical development, nothing is expected in the Gulf Of Mexico over the next few days.

Elsewhere in the Atlantic, a tropical wave continues to head towards the Leeward and Windward Islands this afternoon. To the west of this Tropical Wave, winds are from the northeast. To the east of this wave, winds are from the southeast. With the wave axis or wind shift line is where the showers and storms are located. Heavy rain squalls are the primary threats for the Leewards and Windward Islands over the next day or so. No tropical development is expected as strong southwesterly winds aloft will preclude such occurrance.

The biggest story in the tropics today is out in the western Pacific where a super typhoon continues to make headlines. Maximum sustained winds are near 155 knots with gusts to 190 knots. Super typhoon Dianmu has a minimum central pressure of an estimated 879 millibars. Dianmu is centered near latitude 15.7 north, longitude 135.6 east. Movement continues towards the northwest at near 8 mph. This super typhoon has most likely peaked in intensity. As it interacts with an approaching upper trough, expect some weakening over the next several days. However landfall is still a possibility over central Japan as a strong category 1 or category 2 typhoon. That can still cause damage. This system will continued to be monitored.

I have friends from the Philippines and believe me they don't have the same feelings about these storms

AH...I knew it,it's just me I'm a hurricane freak,I love to see big storms like that,wishing I was in the path of it.
