Plain-language outlook

A cluster of storms well southwest of Hawaii has a moderate chance over the next 7 days to organize into a tropical depression; if that happens it could bring heavier rain and possible flooding near Johnston Atoll by late this week. Another broad area of disorganized showers and storms south-southeast of Hawaii is being watched — if it became a tropical depression or tropical storm later in the week, it could mean increased showers for the southern Hawaiian Islands.
