In the next few days it might be worth keeping an eye on OVATION aurora forecasts again as geomagnetic storms are possible. During higher end events (where Scandinavia widely shows 100% probability), aurora could be seen even beyond areas highlighted on the map. meteologix.com/ee/aurora/eu... TT

Significant rainfall amounts have fallen in parts of Spain over the past days. For example, 84.4 mm of rain fell within a single hour on Sunday in Mas de Barberans. meteologix.com/es/observati... TT

If you listen to the weather forecast on Japanese radio you can still hear cautions about high temperatures and no wonder - in the southern half of Honshu, in Kyushu and Ryukyu Islands, temperatures over 30 degrees were measured today. meteologix.com/jp/observati... TT

In Japan, Izu Islands that just took a serious hit from Typhoon Halong is now due for Typhoon Nakri in the coming hours. Note that satellite imagery for the region is currently coming from Himawari-8 due to a problem with Himawari-9. meteologix.com/jp/satellite... TT

Heavy rain is a topic in Spain along the eastern coast with heavy rain clouds continously moving ashore. Also, a band of training precipitation is currently running through Ibiza. Radar composite centred on Valencian Community: meteologix.com/es/radar-hd/... TT

More tropical trouble in store for Japan. Tropical Storm Nakri (known in Japan as Typhoon Number 23) is expected to reach Ryukyu Islands and then recurve towards the Izu Islands as a Severe Tropical Storm during the coming days. ECMWF storm tracks product: meteologix.com/jp/cyclone-t... TT

It is a sleepless night at Japan's Izu Islands which are currently being affected by typhoon Halong(known as Typhoon Number 22 in Japanese). Here is the latest imagery from Himawari-9, showing Aogashima entering the eyewall: meteologix.com/jp/satellite... TT

Evening update on Storm Amy: Violent wind gusts, 130-150 km/h at exposed locations (and even more in the mountains!) are now spreading into Scotland. Note that many very high readings come from high elevation stations such Aonach Mor. meteologix.com/ie/observati... TT

Storm Amy is now making its presence felt. Gusts to 122 km/h (± rounding) have been reported in Belmullet, Ireland. meteologix.com/ie/observati... TT

A violent storm is expected in UK and Ireland beginning tomorrow. Shown is a scenario of forecast wind gusts from ECMWF through Saturday morning. Exposed locations in Scotland could see wind gusts in excess of 150 km/h: meteologix.com/uk/model-cha... TT

Here is a look at 1 minute infrared satellite imagery from GOES-19 as the core of Hurricane Imelda moves through Bermuda. As the system is undergoing extratropical transition, significant wind gusts are possible even away from the centre. meteologix.com/bs/satellite... TT

Hurricane Imelda is intensifying as it approaches Bermuda for either a landfall or a close approach tonight. The maximum 1 minute average wind speed is 160 km/h according to the latest NHC info. Preparations in Bermuda should be rushed to completion. meteologix.com/bs/satellite... TT

As aurora is underway, here's a handy tool for those fighting with low level clouds - they can be easily tracked using the fog composite in Meteosat data. Example from Estonia: meteologix.com/ee/satellite... TT

Satellite imagery from GOES-19 is showing hurricanes Humberto and Imelda spinning in the Atlantic. While Humberto is becoming extratropical, Imelda is expected to aim towards Bermuda and arrive there at hurricane strength on Wednesday. meteologix.com/bs/satellite... TT

Looks like another night of aurora is in store for Europe as a geomagnetic storm continues and Russel-McPherron effect is enhancing the show. The latest runs from OVATION can be pretty much read as: If it is dark and sky is clear, check the sky! meteologix.com/ee/aurora/eu... TT

Multiple tropical impacts possible in Bermuda during the coming days. Hurricane Humberto is expected to bring tropical storm conditions beginning late Tuesday, followed by tropical storm Imelda which could be a hurricane at that time. meteologix.com/bs/cyclone-t... TT

Looking back at Gabrielle in Azores, here's a graph of reported hourly wind gusts in Horta in Azores. One can also see a dip in wind speeds associated with the passage of the centre of the cyclone. Subtract 1 hour from the timestamps to get local time meteologix.com/pt/observati... TT

Hurricane Gabrielle is now visibly looking disrupted in satellite imagery and might arrive in Azores as post-tropical. However, the threats of violent winds, heavy rain and storm surge continue regardless of the type of cyclone. meteologix.com/pt/satellite... TT

As Hurricane Gabrielle starts undergoing extratropical transition, it is expected to re-intensify and bring significant hurricane force wind gusts to Azores along with heavy rain and storm surge. For example, an ECMWF scenario: meteologix.com/pt/model-cha... (Satellite image: GOES-19) TT

Note: Due to FCI Scan Encoder calibration, there are no new Meteosat-12 images available at present. New images are expected around 15 UTC. Meanwhile, here's imagery from MSG: meteologix.com/ee/satellite... TT

Shown is our Forecast XL product for Horta in Azores, combining model scenarios for wind gusts from various models in a single graph. Impacts from Hurricane Gabrielle will begin late Thursday and will last into Friday. meteologix.com/pt/forecast/... TT

A hurricane watch is in effect for the Azores as Hurricane Gabrielle is expected to impact the islands late Thursday into Friday local time, albeit weaker than now. ECMWF ensemble scenarios of centre path: meteologix.com/pt/cyclone-t... Imagery from GOES-19: meteologix.com/pt/satellite... TT

Hurricane Gabrielle has rapidly intensified into a major hurricane in the Atlantic and could give some passing impacts to Bermuda today. The hurricane is expected to head towards Azores later this week but exact impacts are yet uncertain. Stay tuned. meteologix.com/pt/satellite... (GOES-19) TT

An era has ended in the history of weather satellites. At 15:26:06 UTC, NOAA-15, the last of the POES satellites, went silent as it was decommissioned. Yours truly was able to receive the final image loud and clear from his home office in Estonia using his personal equipment. TT

One area to watch this afternoon in Europe is Catalonia where severe thunderstorms are possible today. Here's a look at the region in the visible and infrared sandwich product using data from Meteosat-12's FCI instrument: meteologix.com/es/satellite... TT
