NASA’s Aqua satellite tv for pc handed over the Japanese Pacific Ocean on Aug. 10 and located that Tropical Storm John had the “wind knocked out of it” because of transferring over cool waters.

At 11 a.m. EDT on Aug. 10, the Nationwide Hurricane Middle or NHC issued the ultimate advisory on John because it weakened to a remnant low strain space.

On Aug. 10. Infrared information from NASA’s Aqua satellite tv for pc analyzed temperature information within the clouds of the previous hurricane that confirmed heat cloud tops and little precipitation.

At 4:45 a.m. EDT (0845 UTC) the Reasonable Decision Imaging Spectroradiometer, or MODIS, instrument aboard NASA’s Aqua satellite tv for pc analyzed Tropical Storm John’s cloud high temperatures in infrared gentle.

MODIS discovered cloud high temperatures of strongest thunderstorms round Kristy’s low-level heart have been solely as chilly as or colder than minus 40 levels Fahrenheit (minus 40 levels Celsius), indicating low clouds and weak uplift of air.

NHC mentioned “John’s convection vanished round 12:30 a.m. EDT (0430 UTC), and the cyclone now consists of a decent swirl of low clouds transferring over a 71.6 levels Fahrenheit (22 levels Celsius) ocean. Given the dearth of convection, the system has been categorised as a remnant low.” Tropical cyclones want ocean temperatures of at the very least 80 levels Fahrenheit (26.6 levels Celsius) to take care of power. Colder temperatures can rapidly sap a tropical cyclone’s power as was the case with John.

The Nationwide Hurricane Middle (NHC) famous at 11 a.m. EDT (1500 UTC), the middle of Publish-Tropical Cyclone John was situated close to 26.eight levels north latitude and 121.1 levels west longitude, about 475 miles (760 km) south-southwest of San Diego.

The post-tropical cyclone is transferring towards the northwest close to 10 mph (17 kph), and this movement is anticipated to proceed till dissipation happens in a few days. Most sustained winds are close to 35 mph (55 km/h) with increased gusts. Further weakening is anticipated.

John could also be fading quick however it’s nonetheless inflicting ocean swells alongside the coast. NHC mentioned “Swells generated by John proceed to have an effect on parts of the Baja California peninsula and southern California. These swells ought to start to step by step subside, however may nonetheless trigger life-threatening surf and rip present situations.”
