Tropical storms are given names when they display a rotating circulation pattern and wind speeds reach 39 miles per hour (63 kilometers per hour). A tropical storm develops into a hurricane when wind speeds go above 74 mph (119 kph). Experts have developed lists of hurricane names for many of the major ocean basins around the world .
Tropical storms are named by the World Meteorological Organization (WMO) picked from a list that rotates every year for 6 years if they display a rotating circulation pattern & wind speeds reaching 39 miles per/hr & when the tropical storm’s wind speeds go above 74 mph its develops into a hurricane.
Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches, and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same basin.
Hurricanes are such a normal part of the tropics season that it can be easy to forget that the modern convention of naming hurricanes started not long ago. The National Hurricane Center began using a naming system to designate storms with maximum sustained winds of 39 mph or more in the Atlantic Ocean in 1979.
Tropical storms require a combination of factors to develop: ocean water warmer than 80°F (26.5°C),an atmospheric disturbance, usually an area of low pressure and cool air, andlow vertical wind shear, meaning that wind speeds must be consistent at different altitudes.
While we were reading we ran into the inquiry “What are some tropical storm names?”.
1960 – tropical storm that passed south of Mexico1968 – short-lived tropical storm that made landfall on Mexico1972 – a Category 1 hurricane that made landfall on Mexico as a tropical storm1976 – a Category 4 hurricane that stayed out to sea1994 – severe tropical cyclone that made landfall southwest of Broome.
How do they pick the names for storms?
The names are: Atiyah, brendan, ciara, dennis, ellen, francis, gerda, hugh, iris, jan, and more items.
What does it mean to invest a tropical weather system?
According to the National Hurricane Center, by designating a tropical weather system as an “Invest”, the collection of specialized data sets and computer model guidance on the area of interest can begin. This collection and processing of data is shown on a number of government and academic websites for analyzing.
Social media and mainstream news media websites along the Gulf Coast have been abuzz this week with the non-starting tropical weather system that forecasters have dubbed Invest 99L. Folks might be confused by the naming of an ominous-looking weather system before it’s even a tropical depression, much less a tropical storm or hurricane.

An invest in meteorology (short for investigative area, alternatively written INVEST) is a designated area of disturbed weather that is being monitored for potential tropical cyclone development.
