Pacific predictions View the weather as it happens across the
vast Eastern and Central North Pacific Animated satellite images of the NE Pacific: Surface pressure for the eastern North Pacific thanks to Ocean Weather. Pressure data taken from the National Center of Environmental Prediction's Aviation Model. These maps are plotted every 3 hours, and are available approximately 1 hour after valid time. Surface winds in the North East Pacific using 'quickSCAT' satellite technology. Surface winds in the vicinity of Hawaii Wind analysis from the University of Wisconsin showing surface, upper and jet stream - or water vapor - winds. As well, there are charts showing wind shear and upper level divergence. For the arm-chair sailor, the low-mid level infra-red winds tell an awful lot about the sea state where the boats are. Colour-coded arrows report wind strengths and direction at different levels. Remember: Friction at the surface slows the wind down a bit, so it will never be as strong at wave height as it shows on the 900hPa chart. The Aviation Weather Centre offers these terrific flight level charts SIGWX) which show the position of jet streams over much of the globe (mostly Northern Hemisphere). Because upper level winds, like the jet stream, steer our weather systems, knowing where these winds are and how they are behaving helps us to understand whether systems are moving east to west quickly or whether they will stalling because of a kink in the pipe-line. Intellicast (a division of Weather Services International) offers this infra-red image of the eastern North Pacific, showing Hawaii and the Gulf of Alaska. Cold cloud tops - indicating heavy rain or snow - are coloured dark red, warmer cloud tops - showing less precipitation - are coloured light yellow. Intellicast also offers an animated loop of the eastern Pacific. The National Oceanographic Data Center in Hawaii issues this great surf and wind forecast for Oahu, thanks to Pat Caldwell. Scripps University offers this animated 72 hour forecast of significant wave heights for the entire Pacific rim. For tropical storm information around the Hawaiian Islands, the Central Pacific Hurricane Center is a good place to start. Hawaiian weather information thanks to NOAA. Animated loop of the Central Pacific - specifically Hawaii, thanks to Weather Services International and Yahoo. This image shows high cloud tops better than surface clouds, but is good for tracking major weather events. West Pacific Surface pressure for the western North Pacific thanks to Ocean Weather. Pressure data taken from the National Center of Environmental Prediction's Aviation Model. These maps are plotted every 3 hours, and are available approximately 1 hour after valid time.South Pacific South Pacific surface pressure from 20 degrees north to 60 degrees south including New Zealand and Chile, thanks to Ocean Weather. Pressure data taken from the National Center of Environmental Prediction's Aviation Model. These maps are plotted every 3 hours, and are available approximately 1 hour after valid time.
