Frequently Asked Questions about Krosa
No, Krosa is no longer active. It dissipated or transitioned into an extratropical cyclone on 2025-08-05T18:00:00.000Z.
Krosa formed on 2025-07-23T12:00:00.000Z and dissipated on 2025-08-05T18:00:00.000Z, reaching a peak intensity of extratropical.
Krosa achieved maximum sustained winds of approximately 148 km/h (80 kt / 92 mph) and a minimum central pressure of approximately 963 hPa.
According to current forecasts, Krosa is expected to pass approximately 176 km from Yokohama, presenting a moderate risk of wind and rain impacts.
According to current forecasts, Krosa is expected to pass approximately 186 km from Tokyo, presenting a moderate risk of wind and rain impacts.
Based on track data, Krosa is expected to remain approximately 532 km from Osaka, with minimal direct threats currently anticipated.
Current forecast data is insufficient to determine direct impacts for Fukuoka from Krosa. Please monitor future track updates.
Projected rainfall totals of approximately 50-150 mm (2-6 inches) may occur in affected areas, creating risks of flash flooding and urban flooding.
Yes. Tropical systems carry abundant moisture, and outer rainbands can trigger flash flooding, river flooding, and urban flooding.
Adjust preparations based on the storm category and official advice. Secure outdoor items, prepare emergency supplies, keep backup power available, and follow official advisories.
Evacuation decisions must strictly follow official directives issued by local emergency management agencies. If an evacuation order is issued, evacuate immediately using designated routes. Do not rely solely on a single forecast model.
StormAtlas regularly updates based on publicly available data from international meteorological agencies. The latest data update was at August 12, 2026 at 05:30 PM.
Krosa developed over warm ocean waters under conditions of high atmospheric moisture and low vertical wind shear.
The forecast path integrates data from multiple international meteorological agencies and numerical weather prediction models (such as NHC, JMA, JTWC, and CMA) using ensemble forecasting methods to generate probabilistic forecast tracks.

Typhoon Krosa (2025): The Crane's Near-Flight Over Japan
The Triple Threat Emerges
In the turbulent theater of July 2025's Pacific, Typhoon Krosa entered stage right as the third dancer in a rare meteorological ballet. While Typhoons F and G dominated headlines, the system designated 12W coalesced near Guam on July 23rd. Christened Krosa ("Crane" in Khmer) by the Japan Meteorological Agency (JMA) on July 24th, this avian-named storm would execute a graceful yet perilous flight path along Japan's doorstep.
The Crane's Fleeting Fury
Feasting on the Marianas' warm waters, Typhoon Krosa rapidly matured. By July 27th, satellite imagery revealed its most majestic form—a tightly wound core with 90 mph (145 km/h) winds circling a 965 hPa pressure eye. This Category 1 peak south of the Ogasawara Islands marked Typhoon Krosa's zenith. Yet even at full strength, dry air saboteurs and wind shear assassins were already gnawing at its structure. The crane's wings would soon be clipped.
Islands in the Storm's Shadow
The Ogasawaras felt Typhoon Krosa's breath first. On July 29th, Chichijima Island watched the storm's eye pass 120 km northeast, its shores battered by 5-meter waves. As Krosa weakened to a severe tropical storm, it turned toward the Izu archipelago. By July 31st, Hachijojima Island lay within its grasp, 200 km west of the churning center. Emergency alerts screamed warnings of 7-meter waves and 126 km/h gusts—the crane's feathers brushing the islands' nerves.
The Kanto Coastline Hold Its Breath
Tension peaked on August 1st as Typhoon Krosa performed its closest approach. 100 km east of Chiba's Boso Peninsula, the storm stirred the ocean into 6-meter monsters while drenching coastal towns with 100mm rains. In Tokyo, ANA flights to Hachijojima vanished from departure boards. Seawall gates slammed shut from Shimoda to Choshi. Yet in a display of meteorological poise, Typhoon Krosa maintained its offshore waltz—the crane's dance avoiding landfall by a feather's breadth.
The Dissipation Tango
Exhausted by its performance, Typhoon Krosa spun northeast into colder waters. On August 4th, the crane completed its final metamorphosis—shedding tropical characteristics to become a post-tropical cyclone. Its once-defined structure dissolved into the North Pacific's canvas, leaving only satellite memories of its 12-day performance.
Legacy of a Near-Miss
Typhoon Krosa's legacy is etched in relief:
Zero casualties despite brushing Japan's most populated region
Minimal damage limited to canceled flights and coastal warnings
Monsoon enhancement that delivered manageable rains to the Philippines
A masterclass in near-miss trajectory that spared mainland Japan
The crane's flight path—1,200 km from Guam to Chiba—served as the 2025 season's ninth act in a record-breaking 27-storm performance. When the curtain fell on August 4th, coastal sirens fell silent, seawalls reopened, and Japan's bullet trains resumed their rhythm. The phantom crane had flown, leaving only ripples in weather archives and a profound lesson in nature's precision.
