how are they forecasted?
By determining the position and strength of high- and low-pressure areas, and predicting how those areas will change during the life of a tropical system.
Tropical cyclone
Because of the forces that affect tropical cyclone tracks, accurate track predictions depend on determining the position and strength of high- and low-pressure areas, and predicting how those areas will change during the life of a tropical system. 
what was the last category 5 hurricane near mexico Hurricane Patricia. when was it formed? Mid-October 2015. where did it hit? Cuixmala, Jalisco, along the Pacific coast of Mexico. what was the impact it created? It affected much of Central America with heavy rain for several days. how are these type of cyclones formed? They typically form over large bodies of relatively warm water, they derive their energy through the evaporation of water from the ocean surface, which ultimately recondenses into clouds and rain when moist air rises and cools to saturation. how does the naming process take place? Names are assigned in order from predetermined lists with one, three, or ten-minute sustained wind speeds of more than depending on which basin it originates. can you name any cyclones that come under this category? Bhola, Nina, Thelma, etc. does it have any codes for identification? Yes, a two-digit number and suffix letter.

Tropical cyclone [SEP] Forecasting
Because of the forces that affect tropical cyclone tracks, accurate track predictions depend on determining the position and strength of high- and low-pressure areas, and predicting how those areas will change during the life of a tropical system. The deep layer mean flow, or average wind through the depth of the troposphere, is considered the best tool in determining track direction and speed. If storms are significantly sheared, use of wind speed measurements at a lower altitude, such as at the 70 kPa pressure surface ( above sea level) will produce better predictions. Tropical forecasters also consider smoothing out short-term wobbles of the storm as it allows them to determine a more accurate long-term trajectory.
