The NHC considers sustained wind speeds to be those that occur over a one-minute period at 10 metres (32.8 ft) above ground. These wind speeds are estimated by using a blend of data from a variety of sources, which include observations from nearby ships, reconnaissance aircraft, or automatic weather stations and pictures from various satellites.

Most commonly (~70% of the time) the limbs are affected first. In this case, neurons in the brain (upper motor neurons) and in the spinal cord (lower motor neurons) are dying and this form is called ``limb onset''. In about 25% of cases, muscles in the face, mouth, and throat are affected first because motor neurons in the part of the brain stem called the medulla oblongata (formerly called the ``bulb'') start to die first along with lower motor neurons. This form is called ``bulbar onset''. In about 5% of cases muscles in the trunk of the body are affected first. In all cases the disease spreads and affects other regions. The symptoms may also be limited to one spinal region.
