The right side of the hurricane is the strongest because a hurricane rotates counterclockwise. As a result the wind speed on the right side is the sum of the speed at which the hurricane is rotating and the storm's forward speed.
The eye is the calmest part of a hurricane. Surrounding the eye is the eye wall, which is the most violent part of a hurricane. The eye wall is almost a complete ring of thunderstorms and contains the strongest winds in the hurricane. Because the hurricane is spinning there is a perceived outward force. This centrifugal force prevents the winds from entering the center of the hurricane. The winds blow as close to the center of the storm as they can and form the eye wall. The winds also help create the storm surge. A high pressure near the top of the hurricane which began as it was forming causes the air in the eye to sink. This is why the weather is nice in the eye. In contrast, the surface pressure near the eye is very low.
