| Episode narrativeepisode_narrative | As Hurricane Beta traversed northward across the Gulf of Mexico in late September, outgoing swell propagated into the lower Texas coastal waters on September 20th through the 22nd. This swell was powerful enough to push water into the dunes across South Padre Island around high tide, which occurred at 7:30 PM CDT on the 20th and 9:37 PM CDT on the 21st. The highest level that was reported was 2.42 feet above Mean Higher-High Water (MHHW; or the level above normally dry ground at the shoreline) at 3:24 AM CDT on the 21st and 2.54 feet above MHHW at 11:24 PM CDT also on the 21st. Levels remained above 1.25 feet MHHW for several hours surrounding the occurrence of high tide on both evenings of September 20th through the 21st and again on the 21st through the 22nd. This activity was enough to cause some coastal erosion.||Farther up the coast, similar wave action and minor coastal flooding was likely - but there were no comparative measurements based on MHHW. |
| Event narrativeevent_narrative | An NWS survey of tidal run-up and overwash on South Padre Island found significant dune erosion at many of City and County beach access points between Isla Blanca Park and Clayton's Beach Bar. Beta's water eroded more dunes that began with run-up associated with Hurricane Laura in late August. Though water levels during the time of the run-up (through the high tide cycle) were above 1.5 feet above Mean Higher High Water (MHHW), the strongest push of wave energy occurred at this time (high combined seas and long period swell from the east). |
