Rip Current Survival Guide

As you start heading out to the beaches, be sure you know how to identify and survive a rip current!

Rip currents are channelized currents of water flowing away from shore at surf beaches. Typically, they form at breaks in sandbars, and also near structures, such as jetties and piers, as well as cliffs that jut into the water. Rip currents are common and can be found on most surf beaches, including the Great Lakes and Gulf of Mexico.

How to Survive a Rip Current:

  • Don’t fight the current. It’s a natural treadmill that travels an average speed of 1-2 feet per second, but has been measured as fast as 8 feet per second—faster than an Olympic swimmer.
  • Relax and float to conserve energy. Staying calm may save your life.
  • Do NOT try to swim directly into to shore. Swim along the shoreline until you escape the current’s pull. When free from the pull of the current, swim at an angle away from the current toward shore.
  • If you feel you can’t reach shore, relax, face the shore, and call or wave for help. Remember: If in doubt, don’t go out!

Hurricanes – Be Prepared!

Hurricanes season runs from June 1 to November 30 each year. Over a typical 2-year period, the U.S. coastline is struck by an average of 3 hurricanes, 1 of which is classified as a major hurricane (winds of 111 mph or greater).

Plan ahead and be prepared!

While hurricanes pose the greatest threat to life and property, tropical storms and depression also can be devastating. The primary hazards from tropical cyclones (which include tropical depressions, tropical storms, and hurricanes) are storm surge flooding, inland flooding from heavy rains, destructive winds, tornadoes, and high surf and rip currents.

  • Storm surge is the abnormal rise of water generated by a storm’s winds. This hazard is historically the leading cause of hurricane related deaths in the United States. Storm surge and large battering waves can result in large loss of life and cause massive destruction along the coast.
  • Storm surge can travel several miles inland, especially along bays, rivers, and estuaries.
  • Flooding from heavy rains is the second leading cause of fatalities from land falling tropical cyclones. Widespread torrential rains associated with these storms often cause flooding hundreds of miles inland. This flooding can persist for several days after a storm has dissipated.
  • Winds from a hurricane can destroy buildings and manufactured homes. Signs, roofing material, and other items left outside can become flying missiles during hurricanes.
  • Tornadoes can accompany land falling tropical cyclones. These tornadoes typically occur in rain bands well away from the center of the storm.
  • Dangerous waves produced by a tropical cyclone’s strong winds can pose a significant hazard to coastal residents and mariners. These waves can cause deadly rip currents, significant beach erosion, and damage to structures along the coastline, even when the storm is more than 1,000 miles offshore.

When a hurricane threatens your community, be prepared to evacuate if you live in a storm surge risk area. Allow enough time to pack and inform friends and family if you need to leave your home.

  • Secure your home: Cover all of your home’s windows. Permanent storm shutters offer the best protection for windows. A second option is to board up windows with 5/8 inch exterior grade or marine plywood, built to fit, and ready to install. Buy supplies before the hurricane season rather than waiting for the pre-storm rush.
  • Stayed tuned in: Check the websites of your local National Weather Service office and local government/emergency management office. Find out what type of emergencies could occur and how you should respond. Listen to NOAA Weather Radio or other radio or TV stations for the latest storm news.
  • Follow instructions issued by local officials. Leave immediately if ordered!
  • If NOT ordered to evacuate:
    • Take refuge in a small interior room, closet, or hallway on the lowest level during the storm. Put as many walls between you and the outside as you can.
    • Stay away from windows, skylights, and glass doors.
    • If the eye of the storm passes over your area, there will be a short period of calm, but at the other side of the eye, the wind speed rapidly increases to hurricane force winds coming from the opposite direction.

JeTSI at AMS 2017

We are pleased to announce that JeTSI team member, Laura Ellen Dafoe, has been selected to provide a presentation at the American Meteorological Society’s 13th Annual Symposium on New Generation Operational Environmental Satellite Systems to be held in Seattle, Washington January 22-26, 2017. Laura Ellen Dafoe will present “Characterization of the Data Volume Generated by the S-NPP Mission to Support Decisions Regarding Data Downlink Resource Management” on Thursday, January 25.

The presentation will take a look at the volume and rate of the data from the six S-NPP data sources analyzed and characterized for the time period April 2012 through December 2015. This characterization supports S-NPP and JPSS Program decisions on satellite data downlink resource management as well as concepts of operations and requirements for future missions. Understanding the variability of the data generation supports optimal and low risk operational decisions on data downlink operations.

Additionally, team members, Dr. Stephen Marley and Laura Ellen Dafoe, are co-authors along with Alexander Werbos (AER) and T.S. Zaccheo on “A Collaborative Approach for Algorithm Operationalization” being presented on Tuesday, January 24.


Environmental Information in Every Decision – EUMETSAT

EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites, Conference is being held this week in Darmstadt, Germany bringing together meteorologists, scientists and researchers from around the world to share their experience and knowledge during plenary, poster and workshop sessions.

Presenting in Poster Session 1, “Environmental Information in Every Decision” by Philip Ardanuy (INNOVIM), David Green (NASA Applied Sciences Program Office), George Komar (NASA Earth Science Technology Office), Dr. Stephen Marley (JeTSI), Peter Neilley (The Weather Business), and Carl Schueler (Schueler Consulting).

In two decades, nearly-deployed constellations of US/European polar-orbiting and geosynchronous meteorological/environmental satellite systems will approach the end of their planned operational lifetimes. As the needs of weather services users continue to grow, they demand a broader suite of applied environmental services. Our ability to deliver these enhanced services is directly coupled to the pace and state of technology maturation. The poster depicts several classes of decisions (public/private; corporate/ commercial; real-time/tactical/strategic) and how intersections of technology maturation and evolving societal needs can drive concepts for exploitation of emerging technologies for, and data collected from, a future satellite observing systems generation.

JeTSI Presentation Accepted – GSAW 2016

Jeffries Technology Solutions, Inc. (JeTSI) is pleased to announce that our submission to GSAW 2016 has been accepted as part of the “Enterprise Approaches” session scheduled for the morning of March 2, 2016 in Los Angeles, California.

Architecture from Concept through Acceptance Test: Reducing Technical Management Costs for Systems-of-Systems” will show how Unified Profile for MoDAF and DoDAF (UPDM) was critical in achieving a new level of technical insight, technical management, and cost control. With the advent of the UPDM in DoDAF 2.0, along with implementations of UPDM provided by various commercial tools (e.g., MagicDraw by No Magic), the long anticipated potential to reduce costs and enhance the technical management of large Systems-of-Systems using “architecture” is beginning to be realized. UPDM’s relational model infrastructure removes the engineers from having to ensure every relationship, every interface, and every perspective remains consistent with each update to the model. This allows the Systems Engineering group to unleash the true power of the “architecture” throughout the life cycle, from Concept Definition and now through Acceptance Testing.

JeTSI has been on the forefront of this new technical management paradigm applying DoDAF modeling to the Constellation Program and providing key support for the Space Network Modernization Ground Sustainment System. Working since 2010 with NASA and NOAA on the Joint Polar Satellite System (JPSS) Ground Project (GP), JeTSI is also leveraging the JPSS GP architecture to assist NOAA’s Office of Satellite Ground Services (OSGS) in charting the overall NESDSIS ground system architecture into the next decade. For both NASA and NOAA, JeTSI has been in a unique position to support major system trades (capability, cost, and schedule) as NOAA charts its new course into the future of weather satellites. This presentation will present the highlights of these efforts, and how UPDM was critical in achieving this new level of technical insight, technical management, and cost control.

The presentation slides will be posted on our website after the conference is held. You will be able to find them in the Published Papers link.
