sustained winds at the FRF approached 17 m/sec, and the maximum 



H (Gage 625) of 3.2 m was recorded at 1700 EST on the 19th. 

 mo 



The lowest barometric pressure reading was 1004 mb at 1300 EST 



on the 16th. Total precipitation was 19 mm. 



g. 9-13 May 1986 (Figure 47). Developing well out in the north 

 Atlantic on 8 May, this storm, in combination with a high- 

 pressure system in central Canada, began to affect the FRF on 

 the same day. As a result of its very slow movement, long- 

 period storm waves (up to 16 sec) were recorded through 13 May, 

 well after local winds had subsided. Winds approached 14 m/sec 



(NE) , and the maximum H (Gage 625) of 3.1 m was recorded at 

 mo 



1800 EST on 10 May. The lowest barometric reading was 



1008.9 mb at 0100 EST on 8 May. There was no precipitation. 



h. 17 August 1986 (Figure 48) . A tropical depression located in 

 the Gulf of Mexico on 12 August slowly tracked across the 

 southeastern US and became stationary off the South Carolina 

 coast early on 15 August. Slowly gaining strength, the low 

 became Tropical Storm Charley early on 16 August with the eye 

 remaining stationary off South Carolina. Reaching minimal hur- 

 ricane strength early on 17 August, Hurricane Charley slowly 

 turned north, gaining speed but not intensity as the day pro- 

 gressed. Charley's eye passed over the FRF between 1530 and 

 1700 EST that afternoon. Wave heights near the end of the pier 

 (Gage 640) remained above 2 m for only 8 hr with heights 

 dropping dramatically following the passage of the eye and the 

 switching of the wind direction. Sustained easterly winds 

 exceeded 24 m/sec with the highest gust reaching 33 m/sec at 

 about 1500 EST. The maximum gust following the eye's passage 



was 24 m/sec from the WSW. The maximum H (Gage 640, 1 km 



mo 



offshore) of 3.4 m (9.8 period) was recorded at 1600 EST. At 



Gaee 630 (6 km offshore), the maximum H was 4.0 m. The 

 e mo 



lowest barometric pressure reading was 988.5 mb at 1530 EST. 



Total precipitation was 81 mm. 



i. 10-12 October 1986 (Figure 49) . Strong NE winds generated by a 

 Canadian high-pressure system first affected the FRF early on 



10 October following the passage of a cold front. Winds 

 reached 15 m/sec (NE) and remained over 10 m/sec for 41 consec- 

 utive hr producing a storm surge of about 0.5 m. The maximum 



H (Gage 640) of 3.3 m (period =8.7 sec) was recorded on 

 mo 



11 October at 0800 EST. Total precipitation was 11 mm. 



2_. 18-19 October 1986 (Figure 50). Developing off Cape Hatteras, 

 NC, early on 16 October, this weak storm travelled slowly up 

 the East Coast and was located off New England early on 

 18 October. The weak storm, in conjunction with a strong high- 

 pressure system center over the Great Lakes, generated strong 

 NNE winds at the FRF on 18 October. Winds peaked near 14 m/sec 



(NNE) at 1500 EST on 18 October with the maximum H 



v ' mo 



(Gage 625) of 2.4 m (period = 9.7 sec) recorded on 19 October 

 at 0400 EST. There was no precipitation.
