I guess this has to do with the lightning and thunder we had last night? The 1.7" of rain was nice to fill up the catchment tank. Got over 2500 gallons.

Would the Flash Flood alert activate the warning sirens?.... because ours (Hamakua coast) went off (single prolonged wail, not a series of shorter wails)at about 3pm and I have not been able to find any other CD alerts online or in the news
