NOAA Satellite, Rainbow Top

NOAA enhanced color photo showing the intensity of the eye, plus the cloud tops surrounding it. The tops of the thunderstorm cloud are extremely high as noted in the areas of black surrounding the eye, resulting from the immense heat content and humidity below. That means it's bearing an incredible amount of rainfall. Compare that against the size of the Big Island, and you'll see why it has emergency management officials concerned. Prepare for high winds, flying objects, excessive rain, flooding, debris, utility outages and road closures. Plan accordingly. If you need it, make sure you have it. Make sure you're in a sheltered location BEFORE winds exceed 39 MPH.
