National Hurricane Center’s Graphical Tropical Weather Outlook for 2 Days and 5 Days, as of June 20, 2017; Updated 6/21/17 with Information on Tropical Storm Cindy

As of June 20, 2017, Tropical Storm Bret was in the Caribbean Sea just north of Venezuela and was predicted to move westward toward Central America through Thursday, June 22.  Bret is the second named storm for 2017 in the Atlantic basin (Atlantic Ocean, Caribbean Sea, and Gulf of Mexico).  At the same time, Potential Tropical Cyclone Three (an area of tropical disturbance that is the potential precursor of a tropical cyclone) was present in the Gulf of Mexico and was expected to develop into a tropical storm within 48 hours and make landfall in Louisiana or Texas by June 22.  [Update 6/21/17 –   Shown below are the National Hurricane Center’s (NHC) two-day and five-day graphical tropical weather outlooks, as of the morning of June 20, accessed at http://www.nhc.noaa.gov/.

Update 6/21/17 – On June 20, Potential Tropical Cyclone Three intensified into Tropical Storm Cindy.  As of the morning of June 21, Cindy was expected to make landfall along the Louisiana or Texas coast late on June 21 or early on June 22, bringing heavy rainfall and flash flooding.  A satelitte photo of Cindy as of about 8 a.m. EDT on June 21 is shown below.

2017 Atlantic Hurricane Season Outlook Released on May 25, 2017, Predicting 11 to 17 Named Storms

The Atlantic hurricane season (including the North Atlantic Ocean, Caribbean Sea, and Gulf of Mexico) runs from June 1 to November 30, with August to October the usual period of peak activity.   On May 25, 2017, the Climate Prediction Center of the National Oceanic and Atmospheric Administration (NOAA) released its outlook for the 2017 Atlantic hurricane season.   The news release on the forecast is available online at http://www.noaa.gov/media-release/above-normal-atlantic-hurricane-season-is-most-likely-year.  The full forecast report is available online at http://www.cpc.ncep.noaa.gov/products/outlooks/hurricane.shtml.

The outlook is a collaboration of the Climate Prediction Center, the National Hurricane Center, and the Hurricane Research Division, all within NOAA.

According to the news release, forecasters predict a 45 percent chance of an above-normal season, a 35 percent chance of a near-normal season, and only a 20 percent chance of a below-normal season.  The outlook also estimated a 70 percent likelihood of 11 to 17 named storms (winds of 39 mph or higher), of which 5 to 9 could become hurricanes (winds of 74 mph or higher), including 2 to 4 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher).  On average from 1966 through 2009, the Atlantic basin has averaged 11 named storms, of which six become hurricanes, with two major hurricanes, according to the National Hurricane Center’s “Tropical Cyclone Climatology” Web page, http://www.nhc.noaa.gov/climo/.  One named storm already occurred in 2017: Tropical Storm Arlene, in April.

NOAA’s full outlook report makes the following cautions about predicted storm numbers: The outlook is “a general guide to the expected overall nature of the upcoming hurricane season; [the outlook] is not a seasonal hurricane landfall forecast, and it does not predict levels of activity for any particular region.   Hurricane disasters can occur whether the season is active or relatively quiet.   It only takes one hurricane (or tropical storm) to cause a disaster.  Residents, businesses, and government agencies of coastal and near-coastal regions are urged to prepare for every hurricane season regardless of this, or any other, seasonal outlook.”

During the season, reports on individual storms as they occur will be available at http://www.nhc.noaa.gov/?atlc.  When storms are completed, reports on individual 2016 storms (including tracks) will be available online at http://www.nhc.noaa.gov/data/tcr/index.php?season=2017&basin=atl.

National Hurricane Center averages for the Atlantic season for the period 1981-2010 are 12 named storms, 6 hurricanes, and 3 major hurricanes. Here are the numbers for the past five years:
2016 – 15 named storms, 4 of which became hurricanes, including 3 major hurricanes;
2015 – 11 named storms, 4 of which became hurricanes, including 2 major hurricanes;
2014 – 8 named storms, 6 of which became hurricanes, including 2 major hurricanes;
2013 – 13 named storms, 2 of which became hurricanes;
2012 – 19 named storms, 10 of which became hurricanes, including 1 major hurricane.

Also on May 27, 2016, NOAA issued its outlook for the Eastern Pacific and Central Pacific basins.  That report is available online at http://www.cpc.ncep.noaa.gov/products/Epac_hurr/Epac_hurricane.html.  For both basins, NOAA estimates an 80-percent chance of a near- or above-normal season.  The eastern Pacific outlook calls for a 70-percent probability of 14 to 20 named storms (6 to 11 hurricanes, including 3 to 7 major hurricanes). The central Pacific outlook calls for a 70-percent probability of 5 to 8 tropical cyclones (tropical depressions, tropical storms, and hurricanes).

1.) Healthy and Safe Swimming WeekMay 22-28, 2017

The week before Memorial Day marks the thirteenth annual Healthy and Safe Swimming Week. Nationwide, communities will be collaborating and engaging in discussion about how to maximize the health benefits of water-based physical activity while minimizing the risk of recreational water–associated illness and injury. Together, swimmers, aquatics and beach staff, residential pool owners, and public health officials can prevent the spread of germs by following easy and effective healthy swimming steps which can be found at www.SwimHealthyVa.com.

The Centers for Disease Control and Prevention (CDC) Web site has promotional materials (brochures, buttons & banners, fact sheets, infographics, podcasts, posters, mobile apps, social media library, stories, and videos) to educate the public on healthy swimming practices.  To learn more, see: http://www.cdc.gov/healthywater/observances/hss-week/index.html.  (Please see #5 below for more resources from the CDC.)

The Virginia Department of Health (VDH) is promoting Healthy and Safe Swimming Week and is providing a media and messaging toolkit at http://www.vdh.virginia.gov/news/toolkits/.  A statewide press release will soon be available at http://www.vdh.virginia.gov/news/public-relations-contacts/news-releases/2017-statewide-news-releases/.

2.) Beach Monitoring in Virginia

Bacteria levels in coastal beach water are monitored weekly at 46 public beaches on the Chesapeake Bay and Atlantic Ocean of Virginia during the swimming season (May-September).

Water samples are collected weekly by Local Health Departments and analyzed by local laboratories for enterococci bacteria. If bacteria levels exceed Virginia’s Water Quality Standard of 104 colony forming units (cfu)/100 mL of water, a swimming advisory is issued. Enterococci bacteria serve as an indicator for fecal contamination in salt and brackish waters. These organisms are not harmful themselves, but indicate that other potentially harmful organisms may be present. High levels of enterococci bacteria indicate an increased health risk to recreational water users.

2010 BP Gulf Oil Spill Ecological Damages Valued at $17.2 Billion, According to Research Published on April 20, 2017

In the April 20, 2017, issue of Science, a team of researchers (including Kevin Boyle of Virginia Tech’s Department of Agricultural and Applied Economics) estimated that the BP Deepwater Horizon oil spill, which began April 20, 2010, resulted in the equivalent of $17.2 billion of damage to natural resources.

The estimate was based on a household survey asking what people would be willing to pay to prevent or reduce a future recurrence of the kinds of damages (to organisms and habitats) seen from the 2010 incident.

The article is “Putting a value on injuries to natural assets: The BP oil spill,” in the April 20, 2017, issue of Science (Vol. 356, Issue 6335, pages 253-254), available online at http://science.sciencemag.org/.  (The direct link to article is http://science.sciencemag.org/content/356/6335/253, but a subscription is required for access.)  A summary of the research is available in BP oil spill did $17.2 billion in damage to natural resources, scientists find in first-ever financial evaluation of spill’s impact, Virginia Tech News, 4/20/17.

An Examination of Antarctic’s Larsen Ice Shelf Changes, in 3/8/17 PBS NewsHour Video

The section-by-section disappearance of Antarctica’s Larsen Ice Shelf is the focus of “How scientists are tracking a massive iceberg in the making,” broadcast on March 8, 2017, on the PBS NewsHour.  The 5 min./55 second video, available online at http://www.pbs.org/newshour/bb/scientists-tracking-massive-iceberg-making/, discusses how an early 2017 rift in the ice shelf is one of the largest ever seen, separating a section approximately the size of the state of Delaware.  This follows the loss in 2002 of a section in that was approximately the size of Rhode Island.  The report describes some of the satellite technology and imagery used to track such large-scale changes.  More information on changes to the Larsen Ice Shelf is available from the National Aeronautic and Space Agency (NASA), “Antarctica’s Changing Larsen Ice Shelf,” online at https://www.nasa.gov/image-feature/antarctica-s-changing-larsen-ice-shelf.
