Typhoon Headed For Fukushima Daiichi

The current model shows typhoon Jelawat headed for Fukushima Daiichi. The model shows it being down to a tropical storm by the time it reaches the Tohoku region but winds of up to 72 mph could still cause problems at the plant. The combination of high winds and considerable rain would delay work, cause more contamination to run off, blow around contaminated debris. If winds are strong enough it could damage unit 1′s tent or cause debris on unit 3 to move. During previous storms TEPCO seemed worried about rainwater flooding the two open spent fuel pools. Unit 4′s spent fuel pool is now covered with a steel plate. Unit 3′s pool is the only one open to rainfall. The typhoon could still take a path that has it more out … Read entire article »

Typhoon Guchol Update Monday June 18

SimplyInfo member Thunder is back with an update on Typhoon Guchol: Typhoon GUCHOL is currently forecast to cross the southern Japanese coastline around 0600UTC/19th of June, most probable impact point will be Shikoku however Kyushu and Tokai are both still at great risk of damaging winds, storm surge and flooding rain. Forecast winds at crossing in excess of 90 knots about exposed coastal areas and up to 70 knots further inland but much of the damaging wind should remain on the south eastern side of the system due to lack of a significant pressure gradient squeeze to the north. Fukushima prefecture should miss the worst of it with the system taking a more western track across Japan before reemerging in the sea of Japan in a significantly weakened state. Forecast rainfall … Read entire article »

Typhoon Guchol Could Hit Honshu Tuesday

SimplyInfo member Thunder has a new weather report on the risk to Japan from Typhoon Guchol: Bad news but it could improve? At the moment Typhoon Guchol is motoring along and current model consensus is above 95% for a crossing of the southern and eastern sections of Japan at or above Typhoon strength, in fact crossing of the Japanese mainland at some point is currently as close to 100% as you can get at this sort of lead time with all computerized weather modeling indicating the same scenario track wise within a few hundred KM’s, only the intensity varies. Currently a category four(SSHS scale) system packing winds in excess of 130 knots the system lies East of the Philippines but is forecast to make the classic northeastern swing in the coming day and … Read entire article »

Elevated Risk Of Tornadoes In Japan Until May 10

Yokosonews is reporting an elevated risk of tornadoes in Japan until May 10th. JMA says a rare case of cold air from Siberia is causing the unstable conditions making tornadoes more likely. They are normally a rare occurrence in Japan. Japan Times explains more about how tornadoes can be formed in Japan. Much of the equipment at Daiichi is on trucks or out in the open without heavy shelter.

Storm Damage At Fukushima Daiichi And Onagawa

Yesterday’s storm that rolled across Japan caused considerable damage, deaths and injuries. Fukushima Daiichi wasn’t totally immune. The tent that covers unit 1 appears to have some minor damage (images below). There are  two existing square openings in one side of the cover. Those two holes appear to now have rips or loose fabric adjacent to the holes. The sustained winds were over the design limits for the reactor cover. This raises questions about the ability to stand up to typhoons. The nitrogen injection system was also halted during the storm for some reason. A worker found the system stopped at 11am JST. More than 12 hours went by before the back up system was running. TEPCO also mentioned an even more worrying fact, it would only take 30 hours for hydrogen … Read entire article »

Storm Hitting Japan Causing Deaths, Damage And Increasing Radiation Readings.

Japan Today is now reporting 3 deaths and 303 injuries associated with the storm passing over Japan today. Trucks have been flipped over, flights canceled and some trains stopped. Winds up to 150km have been seen as the storm moves across the main island. Fukushima Diary is reporting a tornado warning in the region near Tokyo and increases on various radiation station readings as the storm passes those areas. We have been watching the radiation meter at Fukushima Medical University that displays on our website drastically swing up and down. Readings will change as much as .10 uSv between one minute readings.  As of posting this it was reading .40 uSv, it usually is somewhere around the .20 range. The radiation station at Ibaraki (just south of Fukushima) is also now trending up. The Fukushima … Read entire article »

Fukushima To Be Hit With Typhoon Strength Storm Soon

Possibly in the next 8-10 hours a large “low” will come across the sea of Japan, causing high winds at Fukushima Daiichi. It is supposed to hit Tokyo about late afternoon and the following morning in Fukushima. JMA is predicting winds of 25 (meters / second) = 55.9234073 mph. They are also telling people to not go outside during the storm and possibly leave work early to not be caught in it. JMA wasn’t clear if this was the maximum wind, an average or something else. 55mph is generally not considered “devastating”. This wind map shows the predicted winds http://www.kachelmannwetter.de/japan/japan.html Meteo Centrale has very nice live weather pages for Fukushima and Tokyo Street and weather cameras around Tokyo can be found here. Update: 2 dead and 163 injured with gusts up to 150km in western … Read entire article »

Roke Causing Millions To Evacuate, Headed Toward Fukushima Daiichi

New update from Thunder: @ 1200UTC as it transitions to an extra tropical low, Navy NRL have probably stopped sat updates due to this. Final JTWC warning notes the transition and frontal characteristics(looks like a comma shape) first part of the front moved over fukushima prefecture around 1830- 2030JST bringing the highest winds and 1 hour rainfall totals(around 50mm depending on location), @2300JST the rain and wind have significantly lowered over the area with light rain to the west, as this passes it may bring some more rain to the area but not like seen on the eastern side, @ 2000JST the Namie station totals were 164/205/267mm for 12/24/48hr respectively, since it has recorded around 15mm to 2300JST. Hopefully the worst of the system has passed, looking at the sat images … Read entire article »

Roke Upgraded To Typhoon, Today’s Weather Forecast

Roke has increased strength to a typhoon and will cross the southern Japanese coastline in the next 24-30 hours bringing potentially devastating rains to the areas already hammered by Talas earlier this month. The system is expected to significantly weaken on crossing which should mean the strongest winds will only be along the southern coastline, TS strength(34-63kt) winds are still likely to be felt across much of Japan including at the Fukushima NPP, the system will begin extra tropical transtion after crossing pushing the higher wind boundary to the outer bands of the system albeit significantly weakended. The rain will be the problem again, recent microwave sat passes indicate significant potential for falls of 600mm+, precipitation this high should not be widespread and the eventual rainfall patern will depend greatly … Read entire article »

Tropical Storm Roke May Cross Fukushima Daiichi

A weather update by group member Thunder below. We have a group of weather tracking tools on our weather resources page.  I am unsure on TS Roke, forecasts continue to be very shifty even in the short term, models do agree on a Japanese crossing for the system in the next 72-96 hours, JTWC warning track continues to shift accordingly with the model and conditional changes, Roke has been a weird system indeed stalling over Okinawa and dancing around in circles, I think he has given forecasters a nightmare! The problem I see though that while the crossing position continues to change of late all tracks lead across the pile of steaming nuclear rubble know as Fuku npp! Model guidance predicts 200mm+ for Fukushima prefecture(of course it’s only a model- but … Read entire article »

Talas Typhoon Update

Talas’ track is again more westerly then previously forecast(good for fuku npp!), the centre is about to cross the coast. There have been some massive 24 hour rainfall totals recorded along the southern coastline with 20 stations recording above 300mm+ and rank 1 being 710mm recorded at YANASE station (24 hour rainfall record for all of Japan is about 850mm set during Ma-on this year) but the rain remains in sporadic grouping. check at ameras to see, if you are interested - agora.ex.nii.ac.jp . Hopefully fuku npp will continue to dodge the higher rainfall totals and the westerly track will certainly help this! Thanks to Thunder for providing the weather report and links!

Tropical Storm Talas Update

Thanks again to Thunder for providing today’s Talas update: The track has jumped around a little in the last 24 hours, firstly west and now has migrated eastward again a little, models having problem pin pointing what an upper level trough will do in regards to the steering ridge, that is the steering ridge is like a wall of high pressure air, the trough is an elongated area of low pressure, the trough will make a hole in the wall through which the system can pass- weaker trough more western crossing, stronger trough more eastern crossing). JTWC current forecast map about the same as 24 hours ago(now over Kinki instead of Tokai-a little more westerly) the intensity forecast has changed a little too but nothing too major to warant discussion. As … Read entire article »
