Typhoon Krosa joins Super Typhoon Lekima to bring flooding and damaging winds to China, Japan and South Korea

[pavelneuman]

• Update Typhoon Lekima made a landfall in Zhejiang province as a high-end Category 2 storm, with the wind speeds of 177km/h. Here's the latest color-enhanced satellite image from 9 August 2019 at 6 p.m. UTC
  
• Update Lekima weakened to cat. 2 hurricane equivalent and is about to make a landfall in Eastern China. At 2:25 p.m. UTC, Lekima was located approx. 27.30N, 122.5E, with max. sustained winds speeds of 177km/h. Typhoon Krosa was approx. at 22.11N, 141.24E, max. winds 161km/h.
• Update Super Typhoon Lekima was approx. at 27.0N, 122.3E, max. sustained winds 193km/h, typhoon Krosa 22.0N, 141.11E; max. sust. winds 161km/h (9 a.m. UTC). Although the both typhoons are gradually weakening, Lekima remains a serious threat to Eastern China
• Update Super Typhoon Lekima (10W) is forecast to make landfall in Zhejiang province, China later today. At 3 a.m. UTC, Lekima was located approx. 26.23N, 123.24, with max. sustained winds of 209km/h, maintaining its category 4 hurricane equivalent status. Typhoon Krosa (11W) was swirling at 169 km/h, located approx. at 22.0N, 141.5E

• Update 8 August 2019, 8:30 p.m. UTC, Super Typhoon Lekima was located approx. 25.30N, 124.35E, wind speeds of 225km/h. Typhoon Krosa maintained almost the same position in the last 12 hours - at 8:45 p.m. UTC it was approx 22.0N, 141.0E, with sustained wind speeds 177km/h (see the satellite loop below).
• Update At 3 p.m. UTC, Super Typhoon Lekima was located approx. 24.23N, 124.54E with sustained wind speeds of 241km/h. Watch its clear eye in the last 12 hours below.

Earlier Lekima and Krosa coverage

The activity of tropical systems in the Northwestern Pacific Ocean basin is getting more intense again.

Lekima, the first serious typhoon of the season, strengthened to Super Typhoon with sustained wind speed of 241km/h (equiv. to category 4 hurricane), was joined by Typhoon Krosa, that intensified to category 3 equiv. with sustained winds of 185 km/h.

Krosa formed on August 5 as the eleventh tropical depression of the Northwestern Pacific Ocean typhoon season. Meanwhile, Tropical Storm Francisco weakened further.

At 12 p.m. UTC, Lekima was located approximately at 23.36N, 125.30E, with 241km/h wind speeds, Krosa was approx. at 22.6N, 140.35E with wind speeds of 185 km/h.

Typhoon vs. Hurricane + a Nerd Note

A typhoon is the same animal as a hurricane, there’s just different naming in the Western Pacific basin. A typhoon, is a tropical cyclone that has wind speeds ranging from 118 to 220 kph, a super typhoon classification is used when storm's sustained winds goes north of 220 kph.

Therefore, Lekima is equivalent to a Category 4 major hurricane in the North Atlantic Ocean, Krosa is equivalent to Category 3 hurricane.

Josh Morgerman, a hi-profile hurricane chaser, gives you more insights on tropical systems in WPAC basin in his “Nerd Note” on Twitter.

Ambient air pressures in WPAC really are waaaay lower than around N America. Ishigaki is far outside Typhoon LEKIMA (winds are only 22 knots now), yet pressure's already < 980 mb. In the Gulf of Mexico, that would be your reading in the eye of an 85-knot hurricane.

The difference is so huge that when calibrating equipment on WPAC chases, I always feel like my devices are malfunctioning—the pressure readings the day before the typhoon strikes seem too low.
