A Hurricane Watch has been issued for Hawaii County.
SUMMARY OF WATCHES AND WARNINGS IN EFFECT:
A Hurricane Watch is in effect for Hawaii County.
A Hurricane Watch means that hurricane conditions are possible within the watch area. A Hurricane Watch is typically issued 48 hours before the anticipated first occurrence of tropical storm force winds… conditions that make outside preparations difficult or dangerous.
Interests elsewhere in the main Hawaiian Islands should monitor the progress of Madeline. Watches may be required for additional Hawaiian Islands later today or tonight.
