00:00A massive ocean wave thousands of miles wide is on its way,
00:03threatening to raise sea levels and worsen flooding along California's coast this winter.
00:08This slow-moving pulse, called a Kelvin wave, is linked to El Nino,
00:13a shift in Pacific Ocean temperatures that changes weather worldwide.
00:18Unlike beach waves, Kelvin waves don't crash,
00:21but can raise average sea levels enough to increase flood risks,
00:24especially if they coincide with high tides or storms.
00:28Experts warn this wave could hit vulnerable coastal areas, just as storms bring surge and rain.
00:33Meanwhile, El Nino has also quieted the Atlantic hurricane season
00:37by disrupting storm formation with wind shear and downward air currents.
00:42Scientists say this year's El Nino might be the strongest in living memory,
00:47making these effects especially notable,
00:49and a reminder to stay alert to changing coastal conditions.
