7-day Outlook — Central Pacific
Plain-language outlook
The Central Pacific is being watched for two weak systems: one about 785 miles south‑southeast of Hawaii (Invest 91C) has about a 30% chance over the next 7 days to slowly become a tropical depression or weak tropical storm — if that happens it could bring extra rain and a risk of localized flooding to parts of Hawaii late this week. Another system well southwest of the islands (Invest 90C) is being monitored but is poorly organized now and is less likely to develop this week; at most it would mean extra showers well southwest of Hawaii.
