Purpose of Coast Guard Weather

  -- Questions and Answers

The goal of this website is to help those who are interested and willing to put forth an effort to achieve the goals below:

1st….Provide a “how to brief” situational weather overview and, ,
2nd…Provide MST Weather briefers with a more structured learning curriculum, beginning with how to read a surface chart to how to brief aviation weather, both obtaining and briefing pertinent weather hazards. This will allow for interchangeability or “Plug and Play” between aviation units and all sector and subordinate command throughout the entire Coast Guard with regards to planning around the weather.

*************************************************
1) What is Coast Guard Weather?

Coast Guard weather 'CGWX' is specific to the missions within the CG: Maritime Safety, Security, Mobility, National Defense, and Protection of Natural Resources. Other military services have weather support based on amount assets and secrecy of missions carried out. The Coast Guard is the only military service which does not have a weather program, and solely relies on other sources for now 'casts' and fore ‘casts’ of weather. There are vast resources available on the internet, both from Air Force, Navy, NWS and various other sources that renders a formalized weather support system within the CG as not necessary as with other services. However, it is extremely important for CG command to understand what they are looking at. Granted most people do know and understand that when they hear about a Low pressure moving over their AOR in the next few days, this mean inclement weather moving in. Another important aspect of CGWX knows where to get reliable source data; as this is of equal importance in operational risk assessment and situational awareness. From preparing aviation weather briefs to informed incident management, weather is everywhere, and can have profound effects on every mission carried out by CG personnel.

2) Who (what units) need Coast Guard Weather?

All units requiring situational awareness need weather and aviation units requiring weather from a “qualified source” however, only a few aviation units are currently billets for MST’s to provide formalized weather.

Aviation Ashore
Personnel Allowance  
Air Station Kodiak MSTC | MST1 |MST2 | MST2 fixed & rotary wing
International Ice Patrol MSTCS | 2 MST1| 12 other MST's fixed wing only
Aviation Afloat
Personnel Allowance rotory wind only
USCGC Heally MSTC | @ 4 other MST's  
USCGC Sea MSTC | @ 4 other MST's  
USCGC Star MSTC | @ 4 other MST's  

3) What should the structure be?

I have designed CGWX to be knowledge based level of both qualification and competencies.

Level 1: Basic Weather Briefers - CGWXB - CG Weather Briefer: Intended for MSTs at Sectors or anyone required to brief weather to a command for situational awareness…should be open to all rates.

- No previous experience required
- Is open an encouraged for all Coast Guardsmen and women to be familiar with
- is a CORE weather competency; all proceeding Qualification begin with “CGWXB”
       1> Reading a weather chart
            - Surface Station Plot Interpretation
            - What the public wants in a forecast
        2> what is a front?
        3> How are air masses related to fronts and what you need to understand?
        4> What exactly is a front and how does it apply to your weather situation?
        5> Operational weather terminology / Symbology
        6> Where does the information come from for surface charts
        7> Where to get a reliable surface chart – NWS structure
        8> template for a concise weather brief

Level 2: Basic Aviation Weather Briefer - CGAWXB - CG Aviation Weather Briefer: Intended for MST's briefing aviation weather IAW the COMDTINST M3710, and FAA/DOD requirements for a standard weather brief (Dash-1).

- Member must first earn the CGWXB core competency
- The qualification is only open to MST’s serving at a unit providing weather to aviation assets.
- By earning this competency MST’s become interchangeable
- IAW Commandant Instruction Manual 3710.IF It should be understood that MST’s provide a service based on requirements.

COMDTINST 3710_1 (series) Section B. Flight Planning,B.3.b. Weather Clearance
B.3. Weather Briefing Requirements

Weather is an extremely important safety factor in the planning and conduct of flight operations. Paragraphs B.3.a. through B.3.d. of this chapter describe the weather information a PIC must obtain before each flight along with certain record keeping requirements. Section D of this chapter contains information about minimum weather requirements for takeoffs, landings and other aspects of aircraft operations.

B.3.a. General

An aviation weather briefing shall be obtained before all flights. If a weather briefing cannot be obtained prior to departure and the weather conditions are at or above the minimums required for departure, the flight may proceed. The PIC shall contact an appropriate facility for weather information as soon as practicable after takeoff.

B.3.b. Weather Clearance

Weather information entered on aircraft clearance forms shall be supplied by qualified meteorological personnel when such personnel are available. Commanding officers may authorize, in writing, Marine Science Technicians who are graduates of an approved weather briefing school, and who are considered qualified, to prepare and sign flight weather briefing forms.

The basis of this qualification is providing a standard weather brief on a DD form 175-1 Flight Weather Briefing, which is an all inclusive weather package. Knowing each block and what each element means you will have the knowledge to provide an aviation weather brief to pilots. This requirement is set forth not only by Coast Guard, but FAA standards.

Level 3: Local unit qualifications. This qualification reemphasizes key elements of two previous qualifications, and incorporates any local instructions pertaining to how business is accomplished such as unit MISHAP plans. For instance, the IIP has ice observing as their main mission.

- Prerequisites include: CGWXB , and CGAWXB | Kodiak - IIP
- By completing the first two levels, an inherent level of knowledge, creating a solid foundation of learning.
- Air Force weather apprentice school is highly recommended for all MST’s assigned to a unit providing Aviation weather.
- Aspects to the unit level qualification might include other element of weather to include, but is not limited to ice observing, cutter operations, and afloat aviation weather.

Level 4: Aviation Weather forecaster CGAWXF - This qualification is not required. Rather it is put out there for those true weather geeks out there looking to further challenge themselves regarding operational weather and into the realm of forecasting.

- Prerequisite is all three levels AND Air Force Weather school
- Intended to go above and beyond Coast Guard needs.
- This online leaning curriculum is specifically designed for Aviation

5) What should manager the weather program?

This is a tough question, as the members of the Coast Guard in such positions are ever changing. Typically the Course Writer for any rate is the Subject Matter Specialist or SMS. However currently only a select few have formalized training or hold a degree in meteorology (or related Earth Science). The MST rate has a very basic weather curriculum, but is not comprehensive enough to held any one MST as a ‘Program Manager’ (even so a PM is typically an O6 (CAPT). This question remains up for discussion.

6) What kind of training does a briefer need?

Most MSTs that have graduated from “A” school should be more than adequately prepared to begin the basic CGWXB qualification process. Since MSTs are stationed at all Sector commands, it would not be unforeseeable to have a standardized weather brief for each Sector Command, prepared by MSTs which could be distributed to outlying units, as the other services do as well. This would only supplement what is already available via the internet. Otherwise, this site CoastGuardWX.com should contain all necessary information and qualifications for teaching basic briefing and aviation weather to anyone tasked with carrying out this tasking.

7) How do I become qualified and with the competency of CGWXB?

This basic qualification and competency for weather in the Coast Guard is in the infancy stage of development. Therefore what is presented on this site is unofficial at this point. However, I am working with key people at Headquarters to add CGWXB as a basic (core) competency, possibly Coast Guard wide. I do not want to say anything just yet, as these things do change, but I believe the entire CG has a need to understand weather.

For the mean time, CGWXB, has what is applicable to Coast Guard WX knowledge and should surffice to begin anyone needing to prepare weather briefs, or look at weather charts for planning.
