Tsunami warning systems are firing on all of the Hawaiian islands today. An earthquake in Chile of magnitude 8.8 is causing the big wave to ripple across the Pacific. Wave heights are expected to be relatively small, between 3 and 7 feet, compared to the natural tide. Forecasters at the National Oceanic and Atmospheric Administration (NOAA) predict that the tide will rise 5 feet along coastal areas within 15 minutes at about 11:20 am HST. NOAA forecasters are also calling for increased tides in coastal areas along the West coast. If in doubt, move to higher ground.
