Hurricane Beth

{{storm path|Beth 1971 track.png}}

On August 9, a low pressure system in the upper levels of the atmosphere formed off the east coast of Florida. It became a surface low by the next day and acquired the characteristics of a tropical cyclone; it is officially stated to have become a tropical depression at 1200 UTC on August 10. The depression slowly advanced northeastward within a relatively cold environment, and as such, it did not intensify for several days. The system turned more toward the east as it approached the coast of North Carolina, at which time its structure became conducive to further development. On August 14, the depression was declared a tropical storm and assigned the name Beth following recent data from a reconnaissance aircraft.{{cite web|author=Hurricane Specialists Unit|publisher=National Hurricane Center|year=2009|access-date=November 1, 2010|title=Easy to Read HURDAT 1851–2008|url=http://www.aoml.noaa.gov/hrd/hurdat/easyread-2009.html}}{{cite journal|volume=100|issue=4|author=R.

Several hundred miles off the U.S. East Coast, Beth accelerated somewhat – reaching forward speeds of up to {{convert|19|mph|km/h|abbr=on}} as it resumed a northeastward course. Its minimum central pressure deepened to {{convert|990|mb|inHg|lk=on}}, and correspondingly, maximum sustained winds increased. In response, the cyclone was recognized as a Category 1 hurricane. It continued to mature as it passed east of Cape Cod, achieving peak winds of {{convert|85|mph|km/h|abbr=on}} and a pressure of {{convert|977|mb|inHg|abbr=on}}. Subsequently, the hurricane weakened slightly while nearing Nova Scotia. On August 16, it made landfall near Copper Lake before crossing Cape Breton Island. Shortly thereafter, Beth was swept up by a nearby cold front and transitioned into an extratropical cyclone.

In advance of Hurricane Beth, hurricane warnings were issued for coastal and marine areas of Nova Scotia and Newfoundland. In Halifax, bus service was disrupted by the storm, and in Antigonish, business owners closed their stores and filled sandbags to prepare.{{cite news|author=The Canadian Press|title=Nova Scotia awash as rain, storms hit|date=August 16, 1971|newspaper=The Windsor Star|access-date=November 1, 2010|url=https://news.google.com/newspapers?id=O0M_AAAAIBAJ&sjid=rlAMAAAAIBAJ&pg=2155,379553&dq=hurricane-beth+canada+warnings&hl=en}}

The hurricane left extensive damage in its wake, especially to crops and infrastructure.{{cite web|author=Natural Resources Canada |title=Major Hurricanes |publisher=The Atlas of Canada |access-date=November 1, 2010 |url=http://atlas.nrcan.gc.ca/site/english/maps/environment/naturalhazards/naturalhazards1999/majorhurricanes/hurricanes_stats_new.html |archive-url=https://web.archive.org/web/20110602021559/http://atlas.nrcan.gc.ca/site/english/maps/environment/naturalhazards/naturalhazards1999/majorhurricanes/hurricanes_stats_new.html |archive-date=June 2, 2011 }} Halifax International Airport reported {{convert|10.49|in|mm|abbr=on}} of rainfall over 30 hours. The heavy precipitation throughout the country triggered severe flooding, stranding hundreds of travelers. The mayor of Dartmouth reported that the area was a "disaster", as 500 homes were reportedly inundated. Antigonish also experienced significant flooding; waters there approached the top of parking meters.{{cite news|author=The Associated Press|title=Hurricane Beth Pours Rain on Nova Scotia; One Killed|date=August 17, 1971|newspaper=The Spokesman-Review|access-date=November 1, 2010|url=https://news.google.com/newspapers?id=K-0vAAAAIBAJ&sjid=Y-0DAAAAIBAJ&pg=7288,239060&dq=hurricane-beth+canada&hl=en}} Impacted crops in the region included cereal grain, corn, and tobacco, whose inundated fields resembled vast lakes.{{cite web|title=1971 – Beth|publisher=Environment Canada|access-date=February 14, 2011|url=http://www.ec.gc.ca/Hurricane/default.asp?lang=En&n=9027A5DB-1}}

Transport suffered severely: several main roads, including part of the Trans-Canada Highway and Nova Scotia Highway 102, in northeastern Nova Scotia received flood damage and were temporarily blocked off.{{cite news|author=The Associated Press|title=Hurricane Beth Drenches Halifax|date=August 17, 1971|newspaper=Bangor Daily News|access-date=November 1, 2010|url=https://news.google.com/newspapers?id=syw0AAAAIBAJ&sjid=QeEIAAAAIBAJ&pg=2306,465040&dq=hurricane-beth+canada&hl=en}} Additionally, the rising waters washed out several bridges in the region and swept away automobiles. Railways were covered by water, forcing trains to suspend their operation. Drinking water in Dartmouth was contaminated due to excessive runoff into Lake Antigonish, and a trailer park in Antigonish flooded, prompting 600 residents to evacuate.{{cite news|author=The Associated Press|title=Hurricane Blasts Nova Scotia; Flood Damage Is 'Disastrous'|date=August 17, 1971|newspaper=Sarasota Herald-Tribune|access-date=November 1, 2010|url=https://news.google.com/newspapers?id=hvojAAAAIBAJ&sjid=cGYEAAAAIBAJ&pg=7343,209407&dq=hurricane-beth+canada&hl=en}} Overall monetary damage from Beth is estimated at between $3.5 million and US$5.1 million.
