Storm Surge Climatology
Port Lavaca
Time series of storm tide (surge + tide) levels at Port Lavaca above Mean Sea Level (MSL) from 1900-2017 (118 years). Hurricane Harvey likely generated a 10-12 foot storm tide near Port Lavaca, although the highest observed level reported was 7.0 feet above MSL on Sat Aug 26 at 3:48AM CDT. Harvey generated the highest storm tide at Port Lavaca since Hurricane Carla in 1961, and the 5th highest storm tide since 1919. Observations are graphed chronologically from oldest (left) to newest (right). Absence of low-magnitude storm tide events before Ella (1958) is influenced by under-reporting, and does not necessarily indicate a lack of actual storm tide events.
Corpus Christi
Harvey generated the 17th highest recorded storm tide (surge + tide) level on record at Corpus Christi since 1900 and the highest storm tide since Hurricane Alex (2010). Blue dots are storm tide data converted to NAVD88 datum. Data are sorted chronologically from oldest (left) to newest (right). The red circle and line depict Harvey's highest water level in the Corpus Christi area (Bob Hall Pier) as of Fri Aug 25 at 500PM CDT. Higher storm surge levels may have occurred in the Corpus Christi region but have not yet been reported.
