No. Probable cause requires evidence that a crime is taking place or is about to take place, not suspicion that a crime is about to take place. As an example, I remember a story of a judge who threw out a case for lack of probable cause: An officer pulled over someone who had removed their hat after seeing the officer. The officer reasoned that the individual removed his hat to avoid being profiled and stopped by the officer, which the officer deemed suspicious. The judge agreed it was suspicious, but ruled that merely removing one's hat is not evidence of a crime.
