Flash flooding poses a significant risk to small creeks, streams, urban areas, highways, streets, underpasses, and other low-lying or poorly drained areas. Locations at risk include Kipahulu, Kihei, Kula, Pukalani, Makawao, Haliimaile, Keokea, Paia, Puunene, Haiku-Pauwela, and Pauwela. Residents and travelers in these areas should be prepared for rapidly changing conditions and potential road closures. Flash flooding can be life-threatening, especially at night when visibility is reduced.
