From the NASA/GODDARD SPACE FLIGHT CENTER
Now an extra-tropical cyclone over northern Japan, Lan was a typhoon when it made landfall just south of Tokyo over the weekend of Oct. 21 and 22. NASA’s Aqua satellite and NASA-NOAA’s Suomi NPP satellite provided imagery of the extra-tropical cyclone.
On Oct. 23 at 03:42 UTC (Oct. 22 at 11:42 p.m. EDT) NASA-NOAA’s Suomi NPP satellite provided this visible image of Post-tropical cyclone Lan over Hokkaido, Japan. Hokkaido is the northernmost of Japan’s main islands. The image showed the center near Hokkaido while clouds from the western side of the storm extended into the Sea of Japan.
The Atmospheric Infrared Sounder aboard NASA’s Aqua satellite captured an infrared image of Lan on Oct. 23 at 03:53 UTC (Oct. 22 at 11:53 p.m. EDT). Infrared data provides cloud top temperatures and the coldest cloud tops and strongest storms were in eastern Hokkaido.
On Oct. 23 at 0300 UTC (Oct. 22 at 11 p.m. EDT) the Joint Typhoon Warning Center issued the final bulletin on Lan. At that time Lan had maximum sustained winds near 65 knots (74 mph) and was still typhoon strength as an extra-tropical cyclone. Lan was centered near 28.6 degrees north latitude and 143.6 degrees east longitude. That’s about 187 nautical miles south of Misawa, Japan. Lan was speeding to the northeast at 36 knots (41.4 mph/66.6 kph).
The Joint Typhoon Warning Center said “Animated multispectral satellite imagery depicts a well-defined frontal structure with an exposed, broad center and rapidly decaying deep convection sheared to the northeast. Lan is forecast to continue accelerating northeastward within the mid-latitude westerly flow but is forecast to maintain storm-force winds.”

It has been a relatively ‘slow’ typhoon season in the Pacific this year.
When the Atlantic has an active hurricane season, the Pacific has a relatively inactive season…. and vice versa.
The Atlantic had an active September. Other than September it has been oddly quiet.
That seems to work the same way between the northern and southern hemispheres to. BTW Joe Bastardi is warning to look for possible tropical cyclone development in the Caribbean south of Cuba in a few days. Expects it to move N or NE towards Florida or the Bahamas.
NOAA has a 10% X now in that area. I guess only time will tell.
Here’s the animated view from Himawari8 in 30 minute increments (Geocolor), via the RAMMB “slider” tool:

Looks like it mostly missed.
Any ground based wind speeds?
Some things to keep in mind is radioactivity that circulates to Alaska from Japan… Our people are concerned about the wildlife and ocean life between the two nations. Remember the barge that showed up and I believe it was heavily radioactive. The Look a Chernobyl images. Not sure if Atomic power is the way of the future.
Any actual measurements of Fukushima’s radioactivity being spread by Lan?
What ‘highly radioactive barge’???? Cite your source!
“Remember the barge…”
No, I don’t. Can you post a reference?
While you’re at it, please show how much radioactivity Japan currently sends to Alaska.
I’m certain that the causes of the disasters you cite can be avoided in the future through sensible operating practices (as experimentive misoperation caused Chernobyl) and design or engineering modifications. Nuclear can be done safely.
Yes a barge and several parts of Japanese fishing boats washed up on the Washington/Oregon/British Columbia coasts several years after the tsunami. Not ONE of the published news articles about this said anything about any radioactivity above normal background levels.
I hear you Paul. Winds blew Chernobyl disaster fallout north to Scandinavia. I was outside when it drizzled down. Remember well the worst fear at the time – increase in thyroid cancers – and have been following it up since. Now, thyroid cancer is more prevalent in Oceania than in Scandinavia. What can be concluded? It has benefitted my health and might work for you too.
I guess I really shouldn’t be complaining that our Indian summer ended abruptly here in Indiana last night. My furnace ran for the first time this season and my flags on my 30′ pole are stretched out from a cold wet WNW wind.
Despite a persistent drizzle, temps in NJ remain well above normal for this time of year. We were swatting away yellow jackets at my son’s soccer game last Saturday. Supposedly we are on the way to a cooler-than-normal winter but summer is the house guest who won’t leave. Not that I mind so much.
Typhoon Lan should be re-named Typhoon Nothingburger. It started raining on Saturday. At its peak on Monday at 04:00 when I went out to dump garbage, it was Typhoon Zephyr, or maybe Gusty. The rain stopped yesterday (Monday) evening. Today (Tuesday) is sunny and clear.
Had I not read about it and the Yamagata shinkansen not been cancelled, I’d have clocked it as “weather”.
Agreed.
In Ishinomaki yesterday (Monday). Fairly heavy rain and quite windy in the morning. Cleared up mid afternoon. Beautiful day today.
Meanwhile in the Atlantic. There is an extra tropical cyclone at 55.77° N, 29.70° W south of Iceland and west of Ireland. You can see it on https://earth.nullschool.net/.
I have seen no articles or bullitens about it.
“bulletins”
Anthony: Please, an edit function.
Forecast of jet stream indicates the strong impact of winter in the US, which reaches the south to New Mexico.

Here it was an hour or two before landfall. The red areas are highest wind speeds, about 120 km/hr (click anywhere to get stats):

3 hours later, approximate landfall:

So stoked! The surf from this cyclone will be hitting the West Coast late Friday. 22 second interval swells FTW!
