| - Atlantic Canal Hurricanes r Hurricane Season for the Canal started on June 1 - November 30. This year the season started early than expected even powerful than epected. This year, the storms formed in May 22, 2012. Here is the order of the storms. < > First Storm: May 22, 2012 Last storm Dissapted: Season Still Active Storngest Storms: Elisha-878mbar(hPa)(27.77) 185mph Total Depressions: 0 Total Storms: 6 Hurricanes: 3 Major hurricanes( Cat 3+): 3 Total fatalities: 15 direct 10 Indirect Total damage ~ $21 billion Content 1 Seasonal forecasts 1.1 Pre-season forecasts 1.2 Mid-season forecasts 2 Season activity 3 Storms 3.1 Tropical Storm Alberto 3.2 Tropical Storm Beryl 3.3 Hurricane Cruz 3.4 Tropical Storm Debby 3.5 Hurricane Elisha 3.6 Hurricane Florence 4 Storm names 5 Season effects 6 Accumulated Cyclone Energy (ACE) Seasonal forecasts Forecasts of hurricane activity are issued before each hurricane season by noted hurricane experts Philip J. Klotzbach, William M. Gray, and their associates at Colorado State University; and separately by NOAA forecasters. Klotzbach's team (formerly led by Gray) defined the average number of storms per season (1950 to 2000) as 16.6 tropical storms, 5.9 hurricanes, 2.3 major hurricanes (storms reaching at least Category 3 strength in the Saffir-Simpson Hurricane Scale) and ACE Index 96.1.[14] NOAA defines a season as above-normal, near-normal or below-normal by a combination of the number of named storms, the number reaching hurricane strength, the number reaching major hurricane strength and ACE Index.[15] Predictions of tropical activity in the 2011 season Source Date Named storms Hurricanes Major hurricanes Average (1950–2000)[3] 16.6 5.9 2.3 Record high activity 28 15 8 Record low activity 4 2 0† ––––––––––––––––––––––––––––––––––––––––––––––––––––––– TSR December 6, 2011[4] 11–20 5–10 2–3 CSU December 8, 2011[3] 16 9 4 TSR April 4, 2011[5] 10–18 5–10 2–5 CSU April 6, 2011[6] 16 9 5 NOAA May 19, 2011[7] 12–18 6–9 3–5 TSR May 24, 2011[8] 10–18 5–10 2–5 UKMO May 26, 2011[9] 13 N/A N/A CSU June 1, 2011[10] 16 9 5 FSU COAPS June 1, 2011[11] 17 9 N/A WSI July 26, 2011[12] 15 8 4 CSU August 3, 2011 16 9 5 NOAA[13] August 4, 2011 14–19 7–10 3–5 WSI September 21, 2011 21 7 4 ––––––––––––––––––––––––––––––––––––––––––––––––––––––– Actual activity 19 7 4 [edit] Pre-season forecasts On December 8, 2010, Klotzbach's CSU team issued its first extended-range forecast for the 2011 season, predicting well above-average activity with 17 named storms, nine hurricanes, and five major hurricanes. In addition, the team expected an accumulated cyclone energy (ACE) value of approximately 165, citing that El Niño conditions were unlikely to develop by the start of the season. Lastly, the team noted a higher chance for storms to make landfall in the United States than in 2010.[3] In addition, Tropical Storm Risk (TSR), a public consortium that comprises experts on insurance, risk management and seasonal climate forecasting at University College London, issued an extended-range forecast a few days prior to that of CSU, with similar estimates for the year. In its report, TSR noted that tropical cyclone activity could be about 40% above the 1950–2010 average, with 15.6 (±4.3) tropical storms, 8.4 (±3.0) hurricanes, and 4.0 (±1.7) major hurricanes anticipated, and a cumulative ACE index of 141 (±58).[4] On April 6, 2011, the CSU team slightly revised their December forecast, predicting 16 named storms, nine hurricanes, and five major hurricanes.[6] On May 19, 2011, the Climate Prediction Center issued NOAA's outlook for the Atlantic hurricane season. The CPC expected that 12–18 named storms, 6–10 hurricanes, and 3–6 major hurricanes would form in the Atlantic during 2011. The center cited above-normal sea surface temperatures, a weakening La Niña, and the effect of the warm regime of the Atlantic multidecadal oscillation as the basis behind their forecast, adding that seasonal climate models hint that "activity comparable to some of the active seasons since 1995" could occur.[7] On May 26, the UK Met Office (UKMO) issued a forecast of a slightly above-average season. They predicted 13 tropical storms with a 70% chance that the number would be between 10 and 17. However, they do not issue forecasts on the number of hurricanes and major hurricanes. They also predicted an ACE Index of 151 with a 70% chance that the index would be in the range 89 to 212.[9] [edit] Mid-season forecasts On June 1, CSU released their mid-season predictions, with numbers unchanged from those published in April.[10] Concurrently, the Florida State University Center for Ocean-Atmospheric Prediction Studies (FSU COAPS) issued its third annual Atlantic hurricane season forecast, predicting seventeen named storms, nine hurricanes, and an ACE Index of 163. No prediction for the number of major hurricanes was made.[11] Season activity See also: Timeline of the 2012 Atlantic hurricane season In this season, there were 6 tropical cyclones, 6 tropical storms, 6 hurricanes, and 3 major hurricanes. Damage in this season was about $21 billion and there was 100 deaths; a majority of it was caused by Hurricane Elisha and Hurricane Florence. The season's activity was reflected with an above-average cumulative accumulated cyclone energy (ACE) rating of 125.[16] ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength. Subtropical cyclones, including the early portions of Sean, are excluded from the total.[17] Storms Tropical Storm Alberto Tropical storm (SSHS) Duration May 22 – May 29 Intensity 65 mph (100 km/h) (1-min), 993 mbar (hPa) Main article: Tropical Storm Alberto (2012) The origins of Tropical Storm Alberto trace back to a tropical wave that tracked westward across the North Atlantic in late May.[18] It proceeded toward the west-southwest along the North Louisiana coast,[19] bringing heavy rainfall to the area that caused flooding and killed three people.[20][21] By May 27, the disturbance had made landfall at Yucatán Peninsula and emerged back into the water..[22][23] Despite moderate wind shear, it organized over warm waters and was designated as Tropical Storm Alberto at midnight June 29 about 280 mi (450 km) south-southeast of Tampico, Tamaulipas.[24] As it continued to weaken, Albeto began to move to the northeast along a ridge to its north and northwest.[25] Although forecast models supported intensification to tropical depression status. Tropical Storm Beryl Tropical storm (SSHS) Duration May 29 – June 5 Intensity 70 mph (110 km/h) (1-min), 995 mbar (hPa)
