Changes to NOAA marine products made last November and additional changes scheduled for March 7, 2018 will\u00a0 likely make route planning and heavy weather avoidance more difficult for the mariner.<\/p>\n

Changes to the 500 Mb Chart since last November
\n<\/strong>Prior to November 13th, 2017, NOAA depicted TROF axes on its\u00a0500 Mb charts<\/a>, enabling a mariner to relate the upper levels of the atmosphere to the development & movement of surface weather systems, sometimes before they are even noticeable on the charts! See actual 500 Mb & associated Surface Pressure Charts below:<\/h3>\n

 <\/p>\n

After November 13<\/span>th<\/sup>, 2017, the 500 Mb charts now look like what you see depicted to the left, forcing the mariner to figure out for themselves where the TROF axes are likely to be. This change was made mostly without soliciting comments via normal maritime communications channels (e.g., \u201c<\/span>Notice to Mariners<\/strong><\/a>\u201d<\/strong>), thus denying the mariner an opportunity to have their voices heard before theses changes were implemented!<\/span><\/p>\n

For those professional mariners who have been formally trained in NOAA products & services through continuing \u00a0maritime education & training institutions such as the\u00a0Maritime Institute of Technology & Graduate Studies\u00a0(MITAGS)<\/a>, in Linthicum Heights, MD or\u00a0Simulation Training and Research(STAR Center)<\/a>, Dania Beach, Fl & other recognized schools, be advised of new\u00a0 further changes to NOAA products scheduled to go into effect on Wednesday, March 7, 2018.<\/p>\n

Changes in tracking surface systems
\n<\/strong>The current system for tracking all low and high-pressure systems use\u00a0movement arrows showing 24-hours before & 24-hours forward from the \u201cValid Date and Time\u201d for each of the 24, 48, and 96-Hour Surface Pressure Forecast charts. This gives the mariner the ability to not only track each low & high-pressure system through 5-days, but also to see the intensity trends as well.\u00a0\u00a0The new tracking system for the 4 times daily Surface Pressure Analyses charts\u00a0and the 24-48 & 96 Hour Forecast charts will only show the +24-hour forecast position only for those low pressure systems of gale force winds and above.<\/h3>\n

To the right is an explanation of how the surface\u00a0 charts are depicted today plus, below is an actual example of a NOAA 96-hour forecast chart.<\/p>\n

 <\/p>\n

This real time example of a 96-hour surface forecast chart provides tracking of all low & high-pressure systems: 24-hours before and 24-hours ahead of each systems \u201cValid Date & Time. The incremental 24-hour positions are depicted as an \u201cX\u201d for low pressure and a \u201cX\u201d inside a circle for high pressure.\u00a0 Thus, the combination of the 500 Mb charts prior to 13 November 2017 and surface pressure analyses and forecast charts up until 07 March 2018 have been described as a \u201cStandard of Excellence\u201d,<\/em><\/strong>\u00a0by the Director of Training, at the Maritime Institute of Training and Graduate Studies (MITAGS).<\/p>\n

Impact of Changes to NOAA Marine Products
\n<\/strong>The 500 Mb products have been routinely utilized in weather forecasting & vessel route planning. They are now less effective with the removal of the \u201cTROF Axes\u201d.\u00a0 Now, in addition, NOAA will be removing the tracking of all migratory surface low & high-pressure systems\u2026except for those systems that NOAA\u00a0 deems as \u201chazardous\u201d. This change will include all Surface Pressure Analyses & Forecast charts,\u00a0effective on Wednesday, March 7th, 2018. Hereafter, only a forecast position arrow, signifying a low-pressure system moving ahead on the charts \u201cValid Date & Time\u201d (+24-hours) will be depicted on the charts, provided they are (or forecast) to produce at least gale force surface winds (34 knots and higher). This will, in my opinion, increase the risk for a mariner to miscalculate the total weather picture when creating a route plan or when considering route changes.\u00a0 To quote a former Director of Training at MITAGS regarding these changes: \u201cImagine reading a book with every third page missing and trying to piece everything together\u201d<\/strong><\/em><\/h3>\n

\"\"<\/h3>\n

NOAA also wants to increase the oceanic coverage of their colored digital graphic plots of wind information as depicted below (National Digital Forecast Database (NDFD) forecasts). They want to populate more coverage of the north Atlantic and Pacific Oceans within their area of responsibility (SOLAS mandated alpha-numeric text forecasts area of coverage). Once again, this is in lieu of the changes made to the 500 Mb charts & changes to the Surface Pressure Forecasts charts.<\/p>\n

 <\/p>\n

Reasoning and Rebuttal<\/strong>
\nNOAA\u2019s reasoning behind these changes appears not to\u00a0 be based on staffing shortfalls, nor stakeholder demands, but in their stated position to maintain their relevancy.\u00a0NOAA wants to add a 72-Hour Surface Forecast product which would then be inserted between the current 48 & 96 Hours Surface Forecast charts. This may indeed sound logical, however, the downside is the significance of eliminating the tracking system currently in place for ALL MIGATORY SURFACE LOW & HIGH-PRESSURE SYSTEMS! This then would leave surface pressure analyses and forecasts charts uneven when it comes to low and high-pressure system movements (or lack thereof).<\/h3>\n

Today\u2019s NOAA surface pressure analyses and forecasts go out to 168-hours (7-days) via the Weather Prediction Center (WPC). \u00a0Thus adding, for example, a 144-Hour Surface Pressure Forecast (6-day) might be more useful than the planned 72-Hour\u00a0 Surface Pressure Forecast (3 day).\u00a0 A 144-Hour forecast would also be a game changer for vessel route planning and underway route diversions!\u00a0 This would be a substantial upgrade to the current NOAA product suite, as well as enhance training of mariners on using these products via institutions such as MITAGS & STAR Center.<\/p>\n

The depicted colored digital NDFD graphics are not mandated by any IMO or STCW edict, let alone any stakeholder demand. Most importantly, they are also\u00a0not universally accessible on the high seas (outside of high speed Internet range<\/u>)! Once again, NOAA adding the new products jut discussed would be in lieu of the changes made to the 500 Mb charts & the imminent changes to the current Surface Pressure Analysis and Forecasts charts.<\/p>\n

Changes like this can occur without notification, in large part, due to a lack of a process of direct communication and feedback between maritime stakeholder and with NOAA.\u00a0 There may also\u00a0be a lack of understanding of the needs of the maritime industry stakeholders that are engaged in 90 percent of international commerce.<\/p>\n

Lessons learned from the El Faro sinking
\n<\/strong>Some of the recommendations made by the National Transportation Safety Board (NTSB) after the sinking of the El Faro include better optimization of NOAA services to maritime stakeholders\u00a0\u00a0 and a review of the effectiveness of Coast Guard exams and third party provided training. They also tasked the Coast Guard to provide guidance to approved maritime training schools offering operational level training in meteorology to ensure it includes training on the characteristics of weather systems, weather charting and reporting, importance of sending weather observations, sources of weather information, and interpreting weather forecast products.<\/h3>\n

In consideration of lessons learned from El Faro, the changes to NOAA\u2019s analysis and forecast charts will, in effect, make training tasks much more difficult and unnecessary!<\/p>\n

Action Needed<\/strong><\/h3>\n

For those mariners who have been trained well enough to understand and rely on NOAA\u2019s products, the time to let your viewpoints known is NOW, by contacting Benjamin Friedman, Deputy Under Secretary of Commerce for Oceans and Atmosphere ASAP!<\/p>\n

Email:\u00a0 <\/strong>benjamin.friedman@noaa.gov
\n<\/strong><\/a>Phone: 202-482-4569<\/strong><\/p>\n

Notifying congress (e.g., congressmen\/women) & senators as well can have an important effect as well. This is all about accountability from tax foundered service provider(s), in this case NOAA, and the impact on stakeholders (mariners at all levels). This issue must be addressed and acted upon, as to enhance logical decision making in support of SOLAS & IMO objectives & beyond, to minimize weather related incidences & disasters at sea!\u00a0\u00a0 \u00a0 \u00a0<\/strong><\/p>\n

Ask for a\u00a0restoration of 500 Mb TROF Axes and moratorium on planned changes to NOAA marine products on March 7th<\/sup>, 2018 that is urgently needed to allow for constructive dialogue, feedback & consensus solutions!<\/em><\/strong><\/p>\n
