Hawaiʻi faces a possible new tropical storm and a widening food-borne illness investigation, both bad news for residents heading into the peak of an unusually active hurricane season.

• Forecasters give a disturbance east-southeast of Hawaiʻi a strong chance of becoming a tropical depression within days, and it is expected to move west toward the islands.
• The state is investigating a sixth cyclospora case, this time in an Oʻahu resident who had not traveled — pointing to a local source that has not been found.
• The illness causes watery diarrhea; washing hands and rinsing fresh fruit and vegetables cuts the risk.
• The state is also warning about door-to-door solar sellers falsely claiming Hawaiʻi gives away free solar panels and batteries — it does not, and state workers never sell solar door to door.
• CNN mistakenly ran a photo of a Dolly Parton tribute performer while reporting the singer's death, and has apologized to her family.

Outlook: Weather crews will track the system as it turns west this week, while health officials keep hunting for the local food source behind the cyclospora cases.
