The AMA Superbike event at Infineon Raceway will not be affected by rain in 2004, according to weather.com.

The weather forecast for Sonoma, California calls for very little chance of rain over the next 10 days with high temperatures near 80 degrees Fahrenheit each day.

Rain during Friday and Saturday of the 2003 AMA event at Infineon Raceway canceled nearly all practice sessions, washed out all qualifying sessions, caused all classes to be gridded by points and order of entry and forced all races to be run on Sunday.

The effect on-going road construction on Highway 37 between the racetrack and Vallejo, California remains to be seen. Traffic on Highway 37 Friday afternoon was detoured onto surface streets Thursday evening causing long back-ups.

Traditionally, Highway 37 has had long traffic back-ups on race day under normal conditions.
