Hurricane Opal was a major hurricane that formed in the Gulf of Mexico in September 1995. "weather.com - Storm Encyclopedia" (section "Hurricane Opal"), Weather.com, 2007, webpage: [http://www.weather.com/encyclopedia/tropical/archive/1995/storms.html WeatherCom-1995-storms] .] Opal was the 9th hurricane of the abnormally active 1995 Atlantic hurricane season. It crossed the Yucatán Peninsula while still a tropical depression from September 27, then strengthened northward in the Gulf, becoming the most powerful Category 4 Atlantic hurricane before making a second landfall, October 4, in the Florida Panhandle near Pensacola as a 115-mph (185-km/h) hurricane. Opal devastated the Pensacola/Panhandle area with a 15-ft (5-m) storm surge and travelled up the entire state of Alabama, becoming a tropical storm in Tennessee. Opal also caused heavy damage in the mid-Atlantic states before dissipating.

Afterward, 50 people had died from flooding by Opal in Guatemala and Mexico, with another 13 deaths in the United States directly or indirectly related to Opal. Preliminary damage estimates were $3 billion.

The name "Opal" was retired in 1996, replaced by "Olga" for the 2001 season.

Meteorological history

storm path|Opal 1995 track.png The tropical wave that would become Hurricane Opal emerged from the west coast of Africa on September 11. The wave would stay disorganized, and did not begin strengthening until it neared the Yucatán Peninsula, becoming a tropical depression on September 27 while 70 nautical miles (130 km) south-southeast of Cozumel. The depression slowly moved over the Yucatán for the next several days, eventually emerging over the Bay of Campeche, where it was officially upgraded to Tropical Storm Opal.

After languishing for days and nearly dissipating due to the ocean-cooling effect of its own rainfall, it rapidly intensified to a hurricane and began moving north across the Gulf of Mexico. It deepened to a Category 4 hurricane with sustained winds of 150 mph (242 km/h) and a central pressure of 916 mbar (the lowest ever recorded in a hurricane that never reached Category 5 intensity), possibly due to crossing the Loop Current.

During this period of rapid strengthening, a small eye formed with a diameter of only about 6 miles (9.7 km). The hurricane then underwent an eyewall replacement cycle to a 60-mile (97-km) eye, combined with increasing wind shear, causing the pressure to rise steadily over the next 8 hours to 940 mb as the maximum sustained winds diminished to 125 mph (200 km/h). Opal weakened still to 115 mph (185 km/h) before its final landfall in Santa Rosa Island, Florida on October 4.

Opal remained a hurricane for nearly 12 hours after landfall, its rapid forward speed propelling it the entire length of Alabama before being downgraded to a tropical storm as it crossed into Tennessee. Over the following 12 hours, it was not downgraded to a tropical depression until it reached Ohio, and not declared extratropical until reaching Canada, where it still managed to bring squally conditions.

Preparations

This warning was discontinued late the next day. The second was a tropical storm warning issued on October 3 for Morgan City, Louisiana to just west of Pensacola, Florida. A hurricane warning was issued for Mobile, Alabama to Anclote Key, Florida on October 4. This one warning was extended from Mobile, Alabama westward to the Mouth of the Mississippi River including coastal Mississippi. They were extended yet again for Grand Isle, Louisiana westward to just east of Morgan City, Louisiana including Metropolitan New Orleans. All remaining coastal watches and warnings were discontinued on October 5 at 500 UTC.

The post-landfall watches and warnings released in accordance with Opal were a flash flood warning released on October 5 for portions of Alabama, Northern Georgia, the western parts of North Carolina and South Carolina. The warning also included eastern Tennessee. A flash flood watch was also in effect for portions of the Upper Ohio Valley, the Mid-Atlantic region, the central Appalachians and the lower Great Lakes. Wind warnings were in effect for northwestern South Carolina all the way to western New York.cite web

Impact

Mexico and Central America

Damage here was largely attributed to rainfall. Because Opal stalled on the coast of Mexico for several days as a weak tropical storm, flooding was reported across the country, killing 31 people in Guatemala and 19 in Mexico. Rain from the system produced flooding in Tabasco, Campeche, portions of Chiapas, Quintana Roo, and Yucatán.

Florida

About convert|200|mi|km of Florida’s coastline felt effects from Hurricane Opal. [http://www.geocities.com/hurricanene/hurricaneopal.htm Geocities Article on Hurricane Opal] ]

Rainfalls in Florida peaked at convert|15.45|in|mm in Ellyson, convert|7.27|in|mm at Pensacola, convert|6.64|in|mm at Hurlburt Field and lower in over eight different locations. The highest gust recorded was a convert|145|mi/h|km/h|abbr=on gust at Hurlburt Field. Lower gusts were convert|115|mph|km/h at Eglin Air Force Base and an convert|88|mi/h|km/h|abbr=on gust at Pensacola P.N.S. The highest sustained winds were convert|84|mi/h|km/h|abbr=on at Hurburt Field and convert|80|mi/h|km/h|abbr=on at Eglin Air Force Base. The two reported storm surges were convert|5|ft|m to convert|6|ft|m above normal at Apalachicola and convert|2|ft|m to convert|4|ft|m above normal at Sarasota. [http://www.nhc.noaa.gov/1995opal.html Preiliminary Report: Hurricane Opal] ] Opal brought heavy surge to the area, convert|8|ft|m to convert|15|ft|m in some areas, comparing itself to Hurricane Eloise, which struck the same area at near equal strength in 1975.

Opal caused about US$3 billion (1995 dollars) in damage, making it the third costliest hurricane at the time. Most of the structural damage occurred near the coastline on the Florida Peninsula, due to intense surge. Amazingly enough, nearly a mile of U. S. Highway 98 near Eglin Air Force Base was completely destroyed. The pavement was nearly replaced by mounds of sand left behind after storm surge. [ [http://www.geocities.com/hurricanene/hurricaneopal.htm Hurricane Opal 1995 ] ] Opal also spawned an F2 tornado that killed a young woman in Florida. None died as a direct result of storm surge. This is quite unusual, considering the strength and landfall location of Opal. Okaloosa Island, Fort Walton Beach, was overwhelmed by storm surge. Numerous homes were under convert|3|ft|m to convert|10|ft|m of water. Residents were not allowed to return to the island until the homes could be secured from looters. Although a bus tour was arranged by the county so home owners could ‘see’ the damage, but were not allowed off the bus. Looters were found crossing the bay on boats and surfboard, it was feared that some were armed. Sand dunes along the stretch of I-98, normally convert|25|ft|m high, were removed by wind and surge. Where once the ocean was obscured from view by the dunes for miles, a flat open space opened up along U. S. Highway 98.

U.S. Gulf Coast

The peak rainfall from Opal in Alabama was convert|19.42|in|mm three miles east-northeast of Brewton, Alabama. [David M. Roth. [http://www.hpc.ncep.noaa.gov/tropical/rain/opal1995filledrainblk.gifHurricane Opal color-filled, black background rainfall graphic.] Retrieved on 2008-02-24.] Lesser amounts include convert|7.48|in|mm in Mobile and convert|6.1|in|mm in Anniston. The highest gust reported was a convert|95|mph|km/h gust in Fort Rucker and a secondary one at Maxwell Air Force Base with a gust of convert|90|mph|km/h. The highest sustained winds reported from Opal was convert|75|mph|km/h at Fort Rucker, convert|55|mph|km/h in downtown Mobile and convert|47|mph|km/h at Maxwell Air Force Base and Montgomery.

Numerous downed trees across much of the Southeastern United States left over 2 million without power. Alabama reported that 476,000 people were without power, which was a record at the time. This record number of power outages was beaten by Hurricane Ivan in 2004. [http://www.oe.netl.doe.gov/docs/ivan/hurrivan_sitrept_091704_1600.pdf Hurricane Ivan Situation Report #4] ] Damage was heavy all the way inland to Montgomery where winds reached convert|90|mph|km/h.

Highest rainfalls in Mississippi were convert|5|in|mm throughout the eastern side of the state with lower amounts going westward. Tropical storm winds were reported along the Gulf Coast during the afternoon and early evening of October 4. Wind damage was mainly limited to downed tree limbs, power lines, and signs. Property damage cost estimated. One minor injury was reported in Harrison County due to flying debris. Damage in Mississippi totaled up to USD $75 thousand.

In Louisiana, the only significant wind damage occurred in extreme south Plaquemines Parish where winds were estimated around convert|60|mph|km/h with gusts to hurricane force, with wind damage reported to some mobile homes and roofs of a few other structures. Tropical storm force winds, were reported in extreme south Lafourche Parish and Jefferson Parish, as well as extreme east St. Bernard Parish. Property damage cost estimated. Tides were generally convert|2|ft|m above normal in Lake Pontchartrain, and three to five feet above normal along the southeast Louisiana coast from Grand Isle eastward. Some low-lying coastal roads were flooded.

Approximately 10,000 people evacuated from the southern, or lower portions, of Plaquemines, St. Bernard, Lafourche, and Jefferson Parishes. The only significant gathering of persons in public shelters occurred in Plaquemines Parish, where 1,600 people were placed in public shelters.

Although no direct injuries occurred from the hurricane, an indirect injury is attributed to the hurricane in a freak accident. A Jefferson Parish employee was injured while attempting to lower a large flag on October 4. The employee, who was holding onto a rope attached a flag, was tossed high into the air, and suffered severe injuries when he fell back to the ground. Total damage in Louisiana totaled out to US$200,000 (1995 dollars). [http://www4.ncdc.noaa.gov/cgi-win/wwcgi.dll?wwevent~ShowEvent~212824 Event- Hurricane Opal- 04 Oct 1995, 2400 CST] ]

The peak rainfall in Georgia was 8.66 inches (220 mm) in Marietta, 8.08 (205 mm) in Peachtree City and 7.17 (182 mm) in west Atlanta. Southern Georgia only reported 1-3 inches (25-76 mm) of rain, while the northern part of the state reached about 5-7 inches (127-178 mm). The peak wind gust in Georgia was a 79-mph (127 km/h) gust in Marietta, a 70-mph (113-km/h) gust in Columbus, and a 56-mph (90-km/h) gust in the Atlanta-Hartsfield area. [http://www1.ncdc.noaa.gov/pub/data/techrpts/tr9502/tr9502.pdf Hurricane Opal Technological Report] ] High winds in Rabun County caused USD $5.0 million from the approach of Opal on October 5. The damage was worst in Rabun County where numerous trees were blown down. The wind damage was described as being worse than the Superstorm of 1993. Power was out for some people for at least a week. [http://www4.ncdc.noaa.gov/cgi-win/wwcgi.dll?wwevent~ShowEvent~203045 Event-High Winds- 05 Oct 1995, 0300 EST] ] More than 4000 trees were knocked down within the city of Atlanta alone. These trees fell across roads, and on power lines, homes, mobile homes, and automobiles. More than a half a dozen people were injured from falling trees in the early morning hours of October 5. There were more than 1200 telephone poles knocked down and almost 5,000 power lines snapped. Power crews from surrounding states helped to restore power to many, however, thousands of residences remained without power through the weekend.

An 80-foot (24-m) gash was torn out of Interstate 285 between Roswell Road and the Glenridge Connector in Atlanta. Schools were closed on October 5 and October 6 throughout the cities of Atlanta, Marietta, and in Fulton, Coweta, Carroll and Douglas counties. A total of 47 of 101 schools were closed in Dekalb County alone. Four state parks were closed after Opal: Moccasin Creek Park, Black Rock Mountain, Vogel State Park, and Fort Mountain State Park. 273 stations reported many falling traffic lights. Agricultural experts estimated that damage to the pecan crop was about USD $50.0 million. Several rivers and creeks overflowed their banks.

The remnants of Hurricane Opal passed over northwest Pennsylvania on Thursday night (5th/6th) and caused wind gusts up to 50 mph (80 km/h) and sustained winds of 20 to 30 mph (32-48 km/h). Heavy rains accompanied the storm and averaged 1.5 to 2.5 inches (38-64 mm). Flooding was localized and not significant since drought conditions preceded the storm. The prolonged period of strong winds brought down trees and limbs along with some power lines. At least one automobile was damaged by a downed tree in Erie. Several farms reported fields of corn blown down and apples and other fruit being stripped from trees. The actual crop damage estimate was unknown.
