JUNE 1998 MONTHLY REVIEW
June wound up as one of the rainiest and the coolest on record for California in general, with many stations reporting mean temps as much as 15F below normal and significant rains during a season that often sees zero rain. The pattern was mostly a result of a seemingly constant onshore flow resulting from the N-S wind circulation around the eastern flank of the E Pacific High coupled with a series of weak troughs and upper lows (mostly eddy lows) dropping down out of the north on the edge of the E Pacific wind circulation pattern then hanging around endlessly just off the northern Calif/Ore coast. The combination of the effects of the EPH and the cutoff lows is accentuating the onshore push and pulling in ocean air from the WSW and cooler than normal air down from the NNW.. Temps this weekend may bring Snow Levels down to 7,500' - a real rarity this time of year...many Sierra lakes above 8,500' have not unfrozen yet, so with lots more snowmelt to go, rivers are running very high and much colder temperature-wise. Sea Surface Temperatures in near equatorial waters have plummeted almost 14F in recent weeks , from 7 above normal to 7 below normal..heralding in loud measure the arrival of the anticipated La Nina. Hear along the immediate coast, the constant fog and cool NW winds are gradually cooling our waters and are now about normal at 55-56F. However, many flora and fauna after effects from El Nino remain. Grasses are still green in areas where they would be brown long ago, more local sardines are being reported in larger numbers and schools than in memory, fruit trees were very late blooming and small fruit is expected, tomatoes and other hot weather plants are doing very poorly. Garlic yields have been hard hit in the Gilroy area due to ground molds on the bulbs and major damage to strawberries, peaches and nuts have been reported. Wine producers are worried that the cool temps will lower wine quality (and quality) this year. Much above average undergrowth is being reported as a result of the extended Spring rains which have kept grasses alive much longer than usual, and coupled with a low fire season last year, this year there is concern for major fire outbreaks.
