Invest #93W out near Chuuk is looking quite good right now. JTWC gives it a medium chance of becoming a tropical cyclone during the next 48 hours but it may become one much sooner than that at this rate. #Guam needs to keep a close eye on this.

A lifetime animation of Typhoon Sinlaku in the Western Pacific Ocean, from its beginning to post-tropical transition.

Turns out, we've existed for 5 years now. That's pretty neat. To anybody who's stuck with us for these past few years, despite the inconsistent posting as well as not a lot of development going around our side, thank you. Genuinely. We hope to do more and show it to you soon!

Typhoon #Sinlaku ( #04W) – Tropical Cyclone Advisory #19: 1200 UTC 17 April 2026: Sinlaku slowly moving away from the northernmost Marianas. willweatherrva.beehiiv.com/p/typhoon-si...

Typhoon #Sinlaku ( #04W) – Tropical Cyclone Advisory #17: 1200 UTC 16 April 2026: Sinlaku finally moving away from the populated Northern Mariana Islands after relentlessly lashing Tinian and #Saipan for over two days. willweatherrva.beehiiv.com/p/typhoon-si...

Typhoon #Sinlaku ( #04W) – Tropical Cyclone Advisory #15: 1200 UTC 15 April 2026: #Typhoon conditions continuing on Tinian and #Saipan as Sinlaku moves slowly away from the islands. willweatherrva.beehiiv.com/p/typhoon-si...

The National Weather Service in Guam has issued an extreme wind warning for Tinian and Saipan for #Typhoon #Sinlaku ( #04W). This is the earliest such warning on record.

Typhoon #Sinlaku ( #04W) – Tropical Cyclone Advisory #13: 1200 UTC 14 April 2026: Eye of extremely dangerous Sinlaku passing directly over #Tinian and #Saipan. Extreme wind warning issued for those islands. This is a particularly dangerous situation! willweatherrva.beehiiv.com/p/typhoon-si...

Some crazy satellite imagery of Typhoon #Sinlaku ( #04W ) - although it has weakened to a Category 4 #typhoon with 125 kt winds, it is still battering Tinian and Saipan in the Northern Marianas, and the large eye (still undergoing an ERC) is directly over BOTH islands. (images from Dapiya)

#Sinlaku continues its ERC as it closes in on Tinian and Saipan. Conditions are deteriorating at Saipan International Airport with the outer eyewall beginning to come in. Pressures getting quite low and gusts up to near 90kt are being reported! Keep up with surface obs at cyclonicwx.com/storms/

Quite a bit of lightning in Sinlaku’s intense eyewall this morning, or technically evening out there.

Side-by-side perspective of Typhoon Sinlaku's satellite appearance and its estimated intensity as it strengthened from a tropical storm to a category 5-equivalent hurricane. Satellite data via Himawari-9's AHI as provided by NOAA. Intensity estimates are from JTWC hosted by UCAR's RAL.

Super Typhoon #Sinlaku ( #04W) – Advisory #11: 1200 UTC 4/13/26: Outer bands of Sinlaku moving over #Guam and the CNMI. Forecast to pass between #Tinian and #Saipan at or near Cat 5 strength late Tuesday night. This is a particularly dangerous situation! willweatherrva.beehiiv.com/p/super-typh...

#Sinlaku ( #04W)'s 18Z data point in JTWC's best track has been adjusted to an intensity of 160 kts and pressure of 890 mb. Truly insane for a storm in April; this would be lower than Surigae in 2021 that bottomed out at 895 mb.

Super Typhoon #Sinlaku ( #04W) – Tropical Cyclone Advisory #10: 0000 UTC 13 April 2026: Potentially catastrophic Category 5 Sinlaku strengthens a little more while moving northwestward toward the Marianas. This is a particularly dangerous situation! willweatherrva.beehiiv.com/p/super-typh...

Super Typhoon Sinlaku has undergone rapid intensification in the Western Pacific, becoming the strongest storm on Earth so far in 2026. Sinlaku will pass close to and over the Mariana Islands and Guam through the next 24 - 36 hours, delivering catastrophic weather conditions.

Super Typhoon #Sinlaku ( #04W) – Tropical Cyclone Advisory #9: 1500 UTC 12 April 2026: Sinlaku rapidly becomes a potentially catastrophic Cat 5 super typhoon. Typhoon warnings issued for Rota, Tinian, and Saipan. This is a particularly dangerous situation! willweatherrva.beehiiv.com/p/super-typh...

#Sinlaku ( #04W) is an impressive and terrifying tropical cyclone, with winds of 150 kts. Realistically the intensity could be closer to 160-165 kts given sky high automated and manual Dvorak and D-PRINT estimates. Extremely dangerous situation unfolding for the CNMI.

Woah. 📸 CIRA/JMA

Typhoon #Sinlaku ( #04W) – Tropical Cyclone Advisory #8: 0000 UTC 12 April 2026: Sinlaku explosively intensifying and now a Category 3 typhoon. Additional rapid intensification likely today. willweatherrva.beehiiv.com/p/typhoon-si...

#Sinlaku's rapid intensification has been absolutely mind blowing. @UWCIMSS ADT analyzes it with a raw T-number of 7.7 (about 163 kts). Although the actual intensity isn't that high, it is very likely approaching super #typhoon strength. Very dangerous situation for #Guam and the CNMI.

#Sinlaku (#04W) was upgraded to #typhoon status at 18Z, and it appears to be poised for rapid intensification. Microwave satellite imagery from about 1930Z suggests that an inner core has formed with a very small eye feature. This is bad news for #Guam.

Tropical Depression #04W – Tropical Cyclone Advisory #3: 1200 UTC 9 April 2026: Tropical storm warnings and typhoon watches issued for portions of Chuuk State. willweatherrva.beehiiv.com/p/tropical-d...

Tropical depression #04W has just been designated. Currently expected to track northwest near Guam, it may also intensify into a typhoon by Sunday. The JTWC currently estimates that the system has winds of ~45 km/h, with a pressure of 1000 hectopascals. 📸CIRA/JMA

Tropical Depression (Invest #90W) – Tropical Cyclone Advisory #1: 1200 UTC 8 April 2026: Tropical depression forms near Chuuk State. Forecast to move erratically but strengthen significantly during the next few days. willweatherrva.beehiiv.com/p/tropical-d...

New: The April update to the ECMWF seasonal forecast shows an even greater likelihood of a strong El Niño later this year. A few ensemble members go to +3.5 °C anomaly in the Niño 3.4 region!

Cyclone #Maila ( #30P ) is undergoing rapid intensification in an unusual location - meandering in the Solomon Sea. Maila could become quite intense during the next couple of days, and could bring extremely dangerous conditions to Milne Bay Province and Port Moresby in PNG later this week.

Hello, equinox!

Subtropical depression #Samuel / #Jolina has since deteriorated after its landfall earlier today. Gusty winds may continue on its path inland over Libya and Egypt over the coming hours. We've estimated that its winds are at ~45 km/h with its pressure at 998 hPa. 📸 CIRA/EUMETSAT

Subtropical cyclone #Samuel / #Jolina recently made landfall near New Brega, Libya. Rains and winds prevail over the surrounding area, but conditions may improve as the system will rapidly weaken soon. Please stay safe! Winds: ~65 km/h Pressure: 994 hPa 📸 CIRA/EUMETSAT

Subtropical cyclone #Samuel has made landfall near New Brega, Al Wahat, Libya, at around March 18, at around 08:00 UTC. Imagery on CIRA slider is currently slightly delayed, so we unfortunately cannot provide imagery at this time. We may provide imagery later, though.

Subtropical cyclone #Samuel maintains ~65 km/h winds and a pressure of 994 hPa as it heads for Libya, with no further intensification expected. Despite this, we would like to urge the people of Ajdabiya (and nearby areas) to prepare. Please stay safe! 📸 CIRA/EUMETSAT

A recently-formed cyclone over the Mediterranean Sea, now named #Samuel by the National Meteorological Service of Andorra, is expected to approach and make landfall near Benghazi, Libya. Please stay safe! Max winds: ~65 km/h (10-min) Central pressure: 994 hPa 📸 CIRA/EUMETSAT

A subtropical cyclone - often referred to as a #medicane - is located in the Mediterranean Sea off the northern coast of Libya. The system is fairly borderline, but appears well organized and is producing bands of convection fairly near its center. It will move inland and weaken by tomorrow.

What do we have here 👀 Credits to CIRA and EUMETSAT for the imagery!
