Hazardous Coastal Conditions for the Mid-Atlantic; Storm System Approaching Southern Alaska

A Nor'easter will create hazardous marine and coastal conditions along the Mid-Atlantic coast through mid-week, with significant coastal flooding and beach erosion possible. Meanwhile, another strong storm system is forecast to bring high winds and heavy precipitation to portions of southern Alaska. Elsewhere, relatively benign weather is expected through the first half of the work week. Read More >

Hurricane Fern

September 3-13, 1971

A tropical depression formed in the Gulf about 200 miles south of Mobile, Alabama around daybreak on September 3^rd. With weak steering currents, the depression drifted northwest, moving ashore Southeast Louisiana the evening of September 4^th into the early morning hours of the 5^th. Upper level ridging the north caused the weak system to stall and move southwestward, emerging back into the Gulf the afternoon of September 6^th. The depression gradually became better organized, and was upgraded to Tropical Storm Fern the evening of September 7^th.

A gradual weakening in the upper level ridge caused Fern to slow down and begin moving back to the northwest while strengthening into a minimal hurricane the evening of September 8^th. Fern continued to strengthen heading northwest towards the Southeast Texas coast, reaching a peak intensity of 90 mph (80 knots) during the early morning hours of September 9th while located 150 miles south of Galveston, Texas.

Upper level ridging over the Western U.S. began to move eastward, causing Fern to gradually weaken to a strong tropical storm and slow down as it approached the Texas coast just south of Freeport. Fern turned back towards the southwest, making landfall just southwest of Matagorda Bay around Noon CDT September 10th with maximum sustained winds of 70 mph (60 knots) and a minimum central pressure of 979 millibars (28.91 inches). Here is an ATS-3 visible satellite image of Fern at 11:09 AM CDT on September 10, 1971 shortly before landfall. Fern paralleled the Texas coast finally coming ashore near Corpus Christi during the early morning hours of September 11^th. Fern continued to slowly weaken as it moved across South Texas through the morning of September 12^th, dissipating over Mexico later that evening.

WIND & PRESSURE:
The highest winds with Fern occurred along the Texas coast where the center of Fern traversed. Sustained winds of 40 to 60 mph with gusts of 60 to 75 mph were recorded across this area. Further up the Texas coast at the National Weather Service in Port Arthur, the highest sustained winds of 28 mph (24 knots) and a peak wind gust of 36 mph (31 knots) was recorded at 1:01 AM CDT September 10^th. For complete meteorological statistics, see the Wind and Pressure section.

STORM SURGE:
Storm surge values ranged from 3 to 4 feet MSL across coastal Jefferson County in Southeast Texas. Higher readings of 5 to 6 feet MSL were recorded across Galveston Bay to Matagorda Bay. For other storm surge and high-water marks across our region, see the Storm Surge section.

RAINFALL:
Rainfall varied greatly across the region ranging from over 6 inches to less than one half of an inch. The highest total of 6.57 inches was recorded in Morgan City, Louisiana. Much higher rainfall totals of 5 to 26 inches occurred across South Texas, with the highest total of 26.00 inches recorded in Beeville, Texas. For complete rainfall totals reported across our region, see the Rainfall section.
