Hurricanes & Cyclones - RainbowUnicorn - May 2, 2019 Cyclone Fani: India mass evacuations as storm moves up coast Quote:Thousands of people are being evacuated from villages along India's eastern coastline ahead of a severe cyclone. looks bad storm surge is going to be an issue RE: Hurricanes & Cyclones - RainbowUnicorn - May 2, 2019 i suspect the storm surge from the ocean could be quite an issue with "sudden rising water looking like a tsunami killing many people" though i am not sure what a rocky sore line effect would mean RE: Hurricanes & Cyclones - C C - May 2, 2019 "100 million people in the path". Equivalent to a Category-4 hurricane, (215 kph/130 mph with gusts of 260 kph/160 mph). In the past, I guess the density of the population there and arguably less shelter slash less mass mobility would have made it as lethal as a Category-5 grinding up Florida and the gulf coastline. (If not the death and injury impact of the quasi-unofficial Category-6.) Sounds like things may have improved, though, as far as evacuation. Intensity Classifications: . . . Once the system's maximum sustained winds reach wind speeds of 64 knots (74 mph; 119 km/h), the JMA [Japan Meteorological Agency] will designate the tropical cyclone as a typhoon—the highest category on its scale. From 2009 the Hong Kong Observatory started to further divide typhoons into three different classifications: typhoon, severe typhoon and super typhoon. A typhoon has wind speed of 64-79 knots (73-91 mph; 118–149 km/h), a severe typhoon has winds of at least 80 knots (92 mph; 150 km/h), and a super typhoon has winds of at least 100 knots (120 mph; 190 km/h). The United States' Joint Typhoon Warning Center (JTWC) unofficially classifies typhoons with wind speeds of at least 130 knots (67 m/s; 150 mph; 241 km/h)—the equivalent of a strong Category 4 storm in the Saffir-Simpson scale—as super typhoons. However, the maximum sustained wind speed measurements that the JTWC uses are based on a 1-minute averaging period, akin to the U.S.' National Hurricane Center and Central Pacific Hurricane Center. As a result, the JTWC's wind reports are higher than JMA's measurements, as the latter is based on a 10-minute averaging interval. The latter could possibly disparage Fani to not even a true or full Category-4. But the lives lost and devastation probably won't notice the difference. ### |
