Hawaii storm brings 300kmh winds, 40ft waves and snow

According to the National Weather Service in Honolulu, a historic low pressure system impacted Hawaii with strong winds, rain, high surf and snow. According to the NWS, 40ft waves were reported on the facing shores of Oahu.

Here's a brief overview of some of the highest wind speeds and other impacts we experience over the weekend. Unsettled weather looks to stick around though the rest of the week with breezy trades.

According to NOAA National Centers for Environmental Information, Waipa Garden, Kauai beat the previous 24-hours rainfall record with measuring almost 50 inches (1270mm) of rain in 24hrs.

Until recently, high-quality data coverage of the Pacific Ocean was sparse. Now that GOES-17 data is available, however, forecasters have access to more detailed views of high-impact weather systems and other environmental hazards like wildfire smoke and volcanic ash. For example, GOES-17 helps forecasters predict the intensity and impact of Pacific storms that hit the West Coast. These include atmospheric river events that bring heavy rain and high-elevation snow to California and the Pacific Northwest, especially during the winter months. In Hawaii and the central Pacific Ocean, GOES-17’s high-resolution visible and infrared imagery will improve hurricane forecasts and allow meteorologists to better predict areas of intense rainfall. In 2018, Hawaii set a new national rainfall record when 49.69 inches of rain fell in 24 hours. The state also faced several tropical weather threats in what became an active hurricane season in the Central and Eastern Pacific.
