Hurricane: forecasting, preparedness and communication Dr. José Rubiera Director National Forecast Center Institute of Meteorology Havana, Cuba Scientific Conference, Wednesday, July 17th “Impacts of Climate Change, Disasters and Hazards” 1 • Activity Periods, Climate Change and Hurricanes. • Tropical Cyclone Early Warning System in Cuba. A Great Level of Cyclonic Activity have been recorded in the Atlantic basin in the 18-year period 1995 – 2012.

GFDL Simulations: Hurricanes have significantly more near-storm rainfall for warmer climate conditions …(~12% per deg C) More Rainfall Average rainfall in a 32,700 km2 region of highest 6-hour accumulation (equivalent to 100 km radius region).

Source: Landsea, NOAA Accumulated Cyclone Energy (ACE) In 60 – year periods Mid-Atlantic increase could be due to technological artifacts: aircraft and satellite reconnaissance shows a different view. There is no statistically significant evidence so far that this “trend” is any less significant than the overall increase (although a large technological component seems likely) Data quality issues remain unresolved at this time. 13 o It is premature to conclude that human activities--and particularly greenhouse gas emissions that cause global warming--have already had a detectable impact on Atlantic hurricane activity. That said, human activities may have already caused changes that are not yet detectable due to the small magnitude of the changes or observational limitations, or are not yet properly modeled (e.g., aerosol effects). o Anthropogenic warming by the end of the 21st century will likely cause hurricanes globally to be more intense on average (by 2 to 11% according to model projections for an IPCC A1B scenario). This change would imply an even larger percentage increase in the destructive potential per storm, assuming no reduction in storm size. Source: T.R. Knutson, Geophysical Fluid Dynamics Laboratory/NOAA Sept. 3, 2008; Last Revised January 30, 2013 14 o There are better than even odds that anthropogenic warming over the next century will lead to an increase in the numbers of very intense hurricanes in some basins—an increase that would be substantially larger in percentage terms than the 2-11% increase in the average storm intensity. This increase in intense storm numbers is projected despite a likely decrease (or little change) in the global numbers of all tropical storms. o Anthropogenic warming by the end of the 21st century will likely cause hurricanes to have substantially higher rainfall rates than present-day hurricanes, with a model-projected increase of about 20% for rainfall rates averaged within about 100 km of the storm center.

Weather hazards are increasing in intensity and in some of them also in frequency WE DO HAVE TO THINK IN CLIMATE CHANGE! FREQUENCY Tropical Cyclones are the greatest disaster hazard in Cuba CUBA 17 Major Natural Catastrophes in Cuban History have been associated with Hurricanes 1844 and 1846: Two Major hurricanes hit Havana in only two-year in between; more that 100 fatalities in each, destruction of the City in the second. (F. Miahle, 1846) Major Natural Catastrophes in Cuban History have been associated with Hurricanes 1926: A Major Hurricane hit Havana; 600 fatalities 1944: Another Major Hurricane in Havana; 300 fatalities Major Natural Catastrophes in Cuban History have been associated with Hurricanes SANTA CRUZ DEL SUR NOVEMBER 1932 Storm Surge Cat 5 Hurricane Casualties: 3033 The whole city dissapeared under the 6.5 meters high Storm Surge HURRICANE FLORA OCTOBER 1963 Intense Rainfall Total amount: 1 800 mm in 72 hr. Casualties 1159 Great Material Losses, US $300 000 000 (1963 value) 20 Major Natural Catastrophes in Cuban History have been associated with Hurricanes The experiences with Hurricane ¨Flora¨ gave way to the development of: o A modern National Weather Service, o A modern Civil Defense System o A network of dams to store wáter and reduce our vulnerability to floods and droughts 21 Principles in the Cuban EWS • Wide Legal Basis • Clearly defined Mission, Objectives and Functions for each actor in the EWS. • All steps in TC Disaster Management are followed. • Full coordination among main actors • A complete observing system for the country. • Operational manuals regulates all actions in the National Forecast Center. A QMS will be in force since Hurricane Season 2013. • The use of Media by specialists, with graphics and plain, simple words, so that everybody understand the information. And be urged to take actions. 22 Wide Legal Basis Law No. 75 of National Defense Decree-law No. 170 on the Civil Defense system Guideline No. 1 of the Vice President of the National Defense Council Law No. 81 / 97 on the Environment Resolution 106 /99 of the Ministry of Science, Technology and Environment Ordinance Law No. 279 of 2007 "On General Principles, Organization, Preparation and Provisions of the Hydrometeorological System of Cuba for Exceptional Situations 23 1. The National Forecast Center of 2. 3. 4. INSMET and their territorial branches are in charge of monitoring and forecasting Tropical Cyclones Authorities at the different levels of Government, implement protection measures, advised by officials and experts of the Civil Defense. Media and social organizations from National to local level help disseminate the information. Citizens are well organized, educated and prepared. 24 To constantly monitor weather To issue timely Early Warnings to the Government, the Civil Defense, and the people on any hazardous weather system that could affect any part of the Country. To transmit Early Warnings and warnings through the Media, mainly TV and radio, updating the information frequently. To participate in awareness and educational activities 25 CUBA HAS IMPLEMENTED ALL STEPS IN TC DISASTER MANAGEMENT PREVENTIÓN RISK ASSESMENT AND PLANNING PUBLIC EDUCATION PREPARATION RESPONSE RECOVERY PREVENTION AND MITIGATION FORECASTS, EARLY WARNING, WATCHES AND WARNINGS.

The entire region is embedded into a period of high tropical cyclone activity. This current period is stronger than any other previously known, and the amount of major hurricanes is the greatest figure ever recorded. These situation may be worse in a Climate Change environment. 2. Cuba has an Early Warning System for Tropical Cyclones that covers all legal, structural, institutional and public aspects. The strong partnership and interaction among the National Forecast Center (INSMET), the Civil Defense, the Media and the action of an educated people, is the cornerstone of this system. 3. As a result of it, fatalities in tropical storms and hurricanes are a minimum, and the smallest amount recorded in the Americas, despite the intense tropical cyclone activity recorded in the Atlantic area since 1995. 44 Questions?
