It's been a good start to the week in ski country, with resorts all over the west reporting double-digit snow totals from the most recent storm. No one is happier than skiers in drought-ravaged California, where new snow will allow Mammoth Mountain and Tahoe's Mt. Rose to open this week. It's even snowing in Big Bear, where snowmaking crews have the guns blazing and their fingers crossed. Is this the El Niño present sent from the snow gods after four long years of drought? Not so fast, say two California meteorologists.
