Armel Castellan said the first storm system, expected to arrive Thursday, won't bring rains as heavy as those that triggered widespread destruction last week. "With the Thursday system, it is an atmospheric river, tapping into some subtropical moisture and heat. After that system is tapped out, another atmospheric river is expected to follow in short order, hitting Saturday afternoon. A flood watch means river levels are rising and may exceed their banks and flood adjacent areas. The atmospheric river hit the region Saturday.
