Opposite Earth Cyclonic Meteorological Center

The Opposite Earth Hurricane Center is responsible for storms in Opposite Earth's North Atlantic and Northeast Pacific. It was established on September 10, 2019, after the devastation of the 2018-19 Opposite North Atlantic hurricane season. It is headquartered in St. John's. It has trackers and forecasters from both Earth and Opposite Earth because both of those planets are connected together somehow.

Their Scale
Unlike Earth, the Opposite Earth's World Meteorological Organization recommends winds be recorded in a 5-minute average at a height of 10 meters. So all tropical cyclone centers on opposite earth do that, even the OEHC. Here is the scale of the OEHC. The OEHC Hurricane Scale is similar to the Saffir-Simpson Hurricane Wind Scale. A tropical disturbance is designated when an invest has sufficient circulation and has ≤32 mph. A tropical depression can also be designated from an invest straight away, and also can be a disturbance that has been upgraded to have 33-38 mph. Should a tropical depression reach wind speeds of 39 mph, it is designated as a tropical storm and is assigned a name. Once a tropical storm hits 53 mph, it becomes a severe tropical storm. A severe tropical storm is designated a hurricane once it reaches 70 mph. Once a hurricane reaches 90 mph, it becomes a category 2 hurricane. Once a system becomes a category 3, it is designated as a major hurricane. A category 4 hurricane has winds of 125-148 mph. Should the system intensify even further, at 149 mph, it becomes a category 5 hurricane. If it even intensifies more, it becomes a category 6 hurricane at 173 mph. Category 7 is the highest category on the scale and has at least 187 mph in wind speeds. Hurricanes with winds of at least 185 mph are called extreme hurricanes.
