Light showers could hit parts of Los Angeles County beginning late Monday as a low pressure system moves onshore, with some areas across the region expected to get up to an inch of rain on Tuesday, forecasters say. The eastern end of Los Angeles County, including Azusa, could get less than a 10th of an inch of rain starting Monday after 6 p.m., said Kathy Hoxsie, a meteorologist with the National Weather Service. A slight chance of isolated thunderstorms is also forecast.
