APPENDIX D: STORM DATA 



1. This appendix presents a summary of storm data for 1981 collected 



hourly during times when H exceeded 2 m at gage 625, along with a brief 



explanation of the conditions causing the high waves (Appendix B contains 



wave spectra for gage 625 on dates when H exceeded 2 m) . Storm periods 



m 



are detailed in the following paragraphs. 



21 January (Figure Dl) 



2. A low formed over Cape Hatteras, with NNE winds up to 15 m/sec pro- 

 ducing wave heights up to 2.5 m on 21 January. 



11 February (Figure D2) 



3. A high-pressure system, originating over the central US moved east 

 arriving offshore of New England on 10 February. Onshore winds persisted 

 throughout 11 February, resulting in wave heights in excess of 2 m during 

 the day. 



14 February (Figure D3) 



4. A high-pressure system developed on 13 February and remained station- 

 ary over the coast of Delaware and Maryland, producing onshore winds and storm 

 waves during 14 February. 



23-24 February (Figure D4) 



5. A low-pressure system centered over eastern Maryland moved eastward 

 into the Atlantic producing SSE winds on 19 and 20 February; this system con- 

 tinued to affect the coastal wave conditions as it moved offshore. A huge new 

 low developed over Indiana on 22 and 23 February. These two systems resulted 

 in SSE winds of speeds up to 6.7 m/sec and produced 2.8-m, 17-sec waves on 



23 February along the coast.
