What 3 things must occur for a hurricane to get stronger?

For a hurricane to strengthen, three key conditions must be met: warm ocean waters, typically at least 26.5 degrees Celsius (80 degrees Fahrenheit), provide the necessary heat and moisture; low vertical wind shear allows the storm to maintain its structure without being disrupted; and sufficient atmospheric instability enables the storm to continue developing and intensifying. Additionally, the presence of a moist atmosphere at higher altitudes can further support the hurricane's growth.
