Explanation:

Tropical cyclones do not form near the Equator (within 5 degrees latitude) because the Coriolis force is not present and air tends to flow straight into low pressure centers, so it fills up before the pressure can drop enough.
The favourable conditions for the formation of tropical cyclone are given below:
1)   sea surface temperature (26.5 degrees),
2)   sufficient Coriolis force,
3)   low level positive vortices,
4)   weak vertical wind shear of horizontal winds,
5)   large convective instability,
6)   low level convergence of the winds,
7)   huge supply of moisture from the sea surface
