Hurricane Forecasting in Canada: a Partnership Between Research and Operations
Hurricane Forecasting in Canada: a partnership between research and operations J.D. Abraham Director General Weather and Environmental Monitoring Meteorological Service of Canada IWET IV May 24 2012 Creation and evolution of the CHC: 25th Anniversary September 25-28, 1985 – Hurricane Gloria affected the Maritime provinces. Canadians had to rely largely on U.S. forecasts concerning this intense storm. When the storm's effects on Canada were much less than predicted, there was considerable confusion in the media and the general public. This eventually lead to the creation of the CHC. 1980’s CNN – Growth in cable news and live coverage August 31, 1987 – Environment Canada established hurricane centres on each coast: at the then Maritimes Weather Centre (Bedford, N.S.), and at the then Pacific Weather Centre (Vancouver, B.C.). 2000 – The Canadian Hurricane Centre was established in Dartmouth, N.S., to serve all of Canada.

Multi-Scale, Multi-Proxy Investigation of Late Holocene Tropical Cyclone Activity in the Western North Atlantic Basin
Multi-Scale, Multi-Proxy Investigation of Late Holocene Tropical Cyclone Activity in the Western North Atlantic Basin François Oliva Thesis submitted to the Faculty of Graduate and Postdoctoral Studies in partial fulfillment of the requirements for the Doctorate of Philosophy in Geography Department of Geography, Environment and Geomatics Faculty of Arts University of Ottawa Supervisors: Dr. André E. Viau Dr. Matthew C. Peros Thesis Committee: Dr. Luke Copland Dr. Denis Lacelle Dr. Michael Sawada Dr. Francine McCarthy © François Oliva, Ottawa, Canada, 2017 Abstract Paleotempestology, the study of past tropical cyclones (TCs) using geological proxy techniques, is a growing discipline that utilizes data from a broad range of sources. Most paleotempestological studies have been conducted using “established proxies”, such as grain-size analysis, loss-on-ignition, and micropaleontological indicators. More recently researchers have been applying more advanced geochemical analyses, such as X-ray fluorescence (XRF) core scanning and stable isotopic geochemistry to generate new paleotempestological records. This is presented as a four article-type thesis that investigates how changing climate conditions have impacted the frequency and paths of tropical cyclones in the western North Atlantic basin on different spatial and temporal scales. The first article (Chapter 2; Oliva et al., 2017, Prog Phys Geog) provides an in-depth and up-to- date literature review of the current state of paleotempestological studies in the western North Atlantic basin. The assumptions, strengths and limitations of paleotempestological studies are discussed. Moreover, this article discusses innovative venues for paleotempestological research that will lead to a better understanding of TC dynamics under future climate change scenarios. -

1454 MONTHLY WEATHER REVIEW VOLUME 131 ANNUAL SUMMARY Atlantic Hurricane Season of 2001 JOHN L. BEVEN II, STACY R. STEWART,MILES B. LAWRENCE,LIXION A. AVILA,JAMES L. FRANKLIN, AND RICHARD J. PASCH NOAA/NWS/Tropical Prediction Center/National Hurricane Center, Miami, Florida (Manuscript received 19 July 2002, in ®nal form 9 December 2002) ABSTRACT Activity during the 2001 hurricane season was similar to that of the 2000 season. Fifteen tropical storms developed, with nine becoming hurricanes and four major hurricanes. Two tropical depressions failed to become tropical storms. Similarities to the 2000 season include overall activity much above climatological levels and most of the cyclones occurring over the open Atlantic north of 258N. The overall ``lateness'' of the season was notable, with 11 named storms, including all the hurricanes, forming after 1 September. There were no hurricane landfalls in the United States for the second year in a row. However, the season's tropical cyclones were responsible for 93 deaths, including 41 from Tropical Storm Allison in the United States, and 48 from Hurricanes Iris and Michelle in the Caribbean. 1.

FLORIDA HAZARDOUS WEATHER by DAY (To 1994) OCTOBER 1 1969
FLORIDA HAZARDOUS WEATHER BY DAY (to 1994) OCTOBER 1 1969 - 1730 - Clay Co., Orange Park - Lightning killed a construction worker who was working on a bridge. A subtropical storm spawned one weak tornado and several waterspouts in Franklin Co. in the morning. 2 195l - south Florida - The center of a Tropical Storm crossed Florida from near Fort Myers to Vero Beach. Rainfall totals ranged from eight to 13 inches along the track, but no strong winds occurred near the center. The strong winds of 50 to 60 mph were all in squalls along the lower east coast and Keys, causing minor property damage. Greatest damage was from rains that flooded farms and pasture lands over a broad belt extending from Naples, Fort Myers, and Punta Gorda on the west coast to Stuart, Fort Pierce, and Vero Beach on the east. Early fall crops flooded out in rich Okeechobee farming area. Many cattle had to be moved out of flooded area, and quite a few were lost by drowning or starvation. Roadways damaged and several bridges washed out. 2-4 1994 - northwest Florida - Flood/Coastal Flood - The remnants of Tropical Depression 10 moved from the northeast Gulf of Mexico, across the Florida Panhandle, and into Georgia on the 2nd. High winds produced rough seas along west central and northwest Florida coasts causing minor tidal flooding and beach erosion. Eighteen people had to be rescued from sinking boats in the northeast Gulf of Mexico. Heavy rains in the Florida Big Bend and Panhandle accompanied the system causing extensive flooding to roadways, creeks and low lying areas and minor flooding of rivers. -
Hurricane Igor Off Newfoundland
Observing storm surges from space: Hurricane Igor off Newfoundland SUBJECT AREAS: Guoqi Han1, Zhimin Ma2, Dake Chen3, Brad deYoung2 & Nancy Chen1 CLIMATE SCIENCES OCEAN SCIENCES 1Biological and Physical Oceanography Section, Fisheries and Oceans Canada, Northwest Atlantic Fisheries Centre, St. John’s, NL, PHYSICAL OCEANOGRAPHY Canada, 2Department of Physics and Physical Oceanography, Memorial University of Newfoundland, St. John’s, NL, Canada, APPLIED PHYSICS 3State Key Laboratory of Satellite Ocean Environment Dynamics, Second Institute of Oceanography, Hangzhou, China. Received Coastal communities are becoming increasingly more vulnerable to storm surges under a changing climate. 10 October 2012 Tide gauges can be used to monitor alongshore variations of a storm surge, but not cross-shelf features. In this study we combine Jason-2 satellite measurements with tide-gauge data to study the storm surge caused Accepted by Hurricane Igor off Newfoundland. Satellite observations reveal a storm surge of 1 m in the early morning 30 November 2012 of September 22, 2010 (UTC) after the passage of the storm, consistent with the tide-gauge measurements. The post-storm sea level variations at St. John’s and Argentia are associated with free Published equatorward-propagating continental shelf waves (with a phase speed of ,10 m/s and a cross-shelf decaying 20 December 2012 scale of ,100 km). The study clearly shows the utility of satellite altimetry in observing and understanding storm surges, complementing tide-gauge observations for the analysis of storm surge characteristics and for the validation and improvement of storm surge models. Correspondence and requests for materials urricanes and tropical storms can cause damage to properties and loss of life in coastal communities and should be addressed to drastically change the ocean environment1–3. -
Hurricane Michael
Willis Re Hurricane Damage Survey Report Hurricane Michael Executive summary On October 10, Hurricane Michael, the eleventh named storm of 2018, made landfall on the Florida Panhandle as a Category 4 hurricane. More than any other, the cities of Mexico Beach, Lynn Haven and Panama City suffered extensive property damage due to Michael’s extreme winds and storm surge. Extensive infrastructure interruption ensued across the region, including power outages, obstruction of roads and contamination of potable water. Willis Re’s damage reconnaissance team spent four days assessing Michael’s damage. The objective was to research and collect examples of property damage due to wind and storm surge, and to identify elements of properties that exhibited both good and poor resistance. The team traveled nearly 1,000 miles, covering various properties exposed to the storm including in Panama City Beach, Panama City, Lynn Haven, Tyndall AFB, Mexico Beach, Port St. Joe, Apalachicola, South Port, Youngstown, Fountain, Marianna and Tallahassee in Florida; Bainbridge, Georgia; and Dothan, Alabama. In this report, we present their findings. Hurricane Michael’s estimated wind speeds on the ground for Marianna, Panama City, Lynn Haven and Mexico Beach were in the order of 120 mph to 160 mph, above the 700-year return period wind gust according to ASCE 7-10. The majority of homes in Panama City, Lynn Haven, Mexico Beach and Marianna, as to be expected, were not designed to resist 700-year return period wind gusts. In general, the direct wind damage to insured properties that we observed ranged from minor impacts to major structural failures. -
