Since 2009 the Hong Kong Observatory has divided typhoons into three different classifications: typhoon, severe typhoon and super typhoon. [20] 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 ...
602 was the original area code for Arizona, and was split in 1995 into 602, serving metropolitan Phoenix, and 520, serving the remainder of the state. [1] In 1999, 602 was split into 480, 602, and 623, [2] which were recombined in 2023. [3] 520 was split in 2001 to form area code 928. [4]
The West Pacific is the most active and the north Indian the least active. An average of 86 tropical cyclones of tropical storm intensity form annually worldwide, with 47 reaching hurricane/typhoon strength, and 20 becoming intense tropical cyclones, super typhoons, or major hurricanes (at least of Category 3 intensity).

By 1958, the Guam Weather Center had become the Fleet Weather Central/Typhoon Tracking Center on Guam, and had started to name systems as they became tropical storms rather than typhoons. [19] Later that year during the 1958–59 cyclone season, the New Caledonia Meteorological Office started to name tropical cyclones within the Southern Pacific.
In the peak of Atlantic hurricane season, words matter. And using the right ones at the right time can be the difference between alerting of a far-out rotating storm system to a nearer full-blown ...
While many of these storms form in the Atlantic basin, some systems or their remnants move through Mexico from the Eastern Pacific basin. The average storm total rainfall for a tropical cyclone impacting the lower 48 from the Atlantic basin is about 16 inches (410 mm), with 70–75 percent of the storm total falling within a 24-hour period.
A very strong typhoon has wind speeds between 85–104 kn (44–54 m/s; 98–120 mph; 157–193 km/h), while a violent typhoon has wind speeds of 105 kn (54 m/s; 121 mph; 194 km/h) or greater. [8] The HKO, SMG and the CMA also divide the typhoon category into three categories, with both assigning a maximum wind speed of 80 kn (41 m/s; 92 mph ...
In Navajo and Pinal counties, the rainfall damaged roads, bridges, sewers, and homes, which amounted to about $250,000 in repair work for the state of Arizona. [54] October 1972: Hurricane Joanne entered Arizona as a tropical storm before dissipating near Flagstaff. Many areas of the state received between 1 and 3 inches (25 and 76 mm) of ...
