The Maui Emergency Management Agency (MEMA) has upgraded advisories to evacuation warnings for some neighborhoods in ʻĪao Valley and along the Wailuku River due to the risk of flooding from a prolonged kona storm. A shelter at Baldwin High School gym will reopen at 7 PM tonight as a precaution.
Why it matters
Maui has already experienced significant flooding from the first kona storm, leaving flood-impacted areas more vulnerable to further flooding even with less rain. The upgraded warnings aim to protect residents and ensure they have time to evacuate if necessary.
The details

The National Weather Service has a flash flood warning in effect for Maui until 6 PM tonight, and a flood watch through Sunday, March 22. Residents in the affected areas are advised to be on alert and follow county recommendations, with those requiring additional time to evacuate or with livestock and pets encouraged to leave early.
