Cuba is located in the tropics, why does it encounter bad weather such as strong winds and hail?

The main reasons for this kind of weather are as follows: First, cold air activities have been frequent recently; Secondly, due to the influence of high-altitude vortex, this weather system is more likely to appear in May and June. Convective weather is formed because the dry and cold air at high altitude meets the warm and humid air mass at low level. Under the control of this weather system, strong convective weather such as thunderstorm, hail and strong wind is most likely to occur. Thirdly, when there is no rainfall, the ground temperature rises rapidly, which increases the evaporation of water vapor on the ground, and the exchange of cold and warm air intensifies the formation of convective weather.
