Forecast tips for Tomamu
Lead with the 24-hour snowfall column. When cold inland air is the pattern to watch, the live numbers usually matter most in the first lift window. With a 586 to 1171 metre elevation band and 585 metres of vertical, the gladed pockets are the first place to check once the groomers get tracked. A seasonal baseline around 14 metres means the headline numbers can be real storm signals rather than background noise. The swing variable is midday warming, which decides how long the first good surface lasts. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase a settled cold morning after the storm; skip a windy day where the surface never gets a chance to reset.
