REMARKS: HIGHEST WATER DID NOT COINCIDE WITH CLOSEST APPROACH.
PROLONGED MODERATE/STRONG GRADIENT WINDS WELL AHEAD OF MICHAELS
CIRCULATION LED TO THE HIGHEST WATER LEVELS.

NOS GAUGES ARE REFERENCED TO MHHW. THIS CAN RESULT IN A MAXIMUM
SURGE VALUE GREATER THAN THE MAXIMUM TOTAL WATER LEVEL IF THE
PREDICTED WATER LEVEL AT THE TIME OF MAXIMUM STORM TIDE WAS
NEGATIVE.

USGS GAUGES DO NOT HAVE PREDICTED TIDE LEVELS. SURGE IS ESTIMATED
BASED ON PRE-EVENT WATER LEVELS.
