studded Baja California peninsula on Monday. Mexico issued a hurricane watch for the southern portion of Baja, meaning hurricane conditions are possible within 36 hours, according to a report of The Associated Press. Jimena, a dangerous Category 4 storm, could rake southern Baja California by Tuesday evening, forecasters said. "I think it's going to be a substantial hurricane by the time it approaches," said Richard Pasch, a senior specialist with the National Hurricane Center in Miami.
