 **System Enhancement of Lake Side Breezes** \\ Because there are no buildings or trees to slow surface winds over the lake, onshore breezes are often stronger at the lake than inland. This lack of surface friction is also the reason why system winds off the lake seem to blow so hard. **System Enhancement of Lake Side Breezes** \\ Because there are no buildings or trees to slow surface winds over the lake, onshore breezes are often stronger at the lake than inland.

 **Watch for the Dreaded Transition Zone** \\ A transition zone is the area where the lake breeze meets the system breeze. This convergence of wind directions often creates an area of little or no wind. This moves around during the day as the lake breeze builds and subsides. You often see a near shore transition zone in the late morning and early evening as the lake breeze forms or dies. **Watch for the Dreaded Transition Zone** \\ A transition zone is the area where the lake breeze meets the system breeze.
