 A small craft advisory is now in effect as ASCAT showed 20 knot
 winds in our western waters. Winds will remain gusty and offshore
 through tonight with the SCA ending at 09Z tonight. With the
 offshore flow there is a possibility for a low water event (-1.0
 ft below MLLW) during low tide on Friday morning. For the weekend
 conditions will improve before another cold front brings more
 gusty offshore winds on Monday.
