For the same reason that you see lightening before you hear the thundering sound it makes. Light travels faster than sound through the air.

How fast is a nuclear explosion?
The explosion itself is over within a few microseconds, but it takes milliseconds to seconds for the fireball to expand to full size. The blast wave travels as a supersonic shock wave. Fires ignite later, mostly from fire sources knocked over or broken by the blast (the blast blows out initial direct flash fires before they can spread).
A soldier hears the sound of a distant cannon 6 seconds after he sees the flash How far away is the cannon?
Using the speed of sound at 20° C, which is 343 m/sec, the cannon would be 2058 meters away. Temperature, pressure, and humidity could all affect the actual speed.
Why lightning is seen before thunder is heard?
Sound (thunder) travels much much slower than light (lightning flash).
Examples to show that light travels faster than sound?
An example that shows light travels faster than sound are: - You see the lightning before you hear the thunder. - You see the light coming from the lighthouse before you hear the foghorn. Unless the storm is right overhead, you will see the lightning before you hear the thunder. An experiment you can do to prove that light travels faster than sound is you can ask your friend to turn on a torch and make a huge noise at the same time from quite a distance from where you are standing. If you have a large distance between you and your friend, you will probably see the light before you hear the sound.
How would you calculate the speed at which a thunderstrom cell is moving?
Count the time in seconds between a lightning flash and the thunder clap. Five seconds delay equals 1 mile in distance.
