Warning Requirements


Chief of Naval Education and Training (CNET)

1. Warnings are issued for CNET's area of responsibility as directed by the Commander, Navy Region Southeast, who serves as the Regional Planning Agent (RPA) for all regions in the eastern U.S. CNET serves as a Sub-Regional Planning Agent (SRPA) for the Sub-Region CHARLIE Areas.

2. As SRPA, CNET, based on the recommendation of the NAVTRAMETOCFAC Commanding Officer (CO) or Hurricane Duty Officer (HDO), sets all Tropical Cyclone Conditions of Readiness (COR) for Sub-Region CHARLIE Areas C1, C2, C3, and C4. Dissemination of a change in a COR is implemented by CNET by a message as well as use of the NAS Operations Plan (OPLAN) phone tree. Attainment reports by notified activities will be made to the Disaster Preparedness Office (DPO). As coordinated with the DPO, attainment reports may be made via the NAVTRAMETOCFAC web site at www.ntmof.navy.mil/dpo.

Tropical Cyclone Cond. V Seasonal set from 01 JUN -30 NOV
Tropical Cyclone Cond. IV within 72 hrs.
Tropical Cyclone Cond. III within 48 hrs.
Tropical Cyclone Cond. II within 24 hrs.
Tropical Cyclone Cond. I within 12 hrs.

Note: Conditions I-IV are set when destructive force winds of 50 knots or higher are possible or anticipated in the time period indicated. (p)3. Per CNET directive, NAVTRAMETOCFAC sets all non-tropical weather warnings/conditions (defined below) for Sub-Region CHARLIE Areas C1, C2, and C3. These warnings are set by the NAVTRAMETOCFAC Forecast Duty Officer (FDO) without a prior recommendation to CNET. Dissemination of non-tropical weather warnings is executed by activation of phone tree call lists at the various commands. The Pensacola Naval Complex is located within Area C2 and includes the following activities:

-NAS Pensacola
-NTTC Corry Station
-Naval Education and Training Professional Development and Technology Center (NETPDTC) Saufley Field
-NASP tenant commands
-Naval Outlying Field (NOLF) Choctaw
-Naval Aerospace Medical Research Laboratory (NAMRL)
-Naval Hospital Pensacola (NAVHOSP Pensacola)


Storm Cond. II within 24 hrs. 48+ knot winds expected
Storm Cond. I within 12 hrs. 48+ knot winds expected
Gale Cond. II within 24 hrs. 34-47 knot winds expected
Gale Cond. I within 12 hrs. 34-47 knot winds expected

High Wind Advisory:

Cond. II within 24 hrs 18-33 knot winds expected
Cond. I within 12 hrs 18-33 knot winds expected

Small Craft Warnings are issued for 18-33 knot winds affecting bays, coastal areas, and inland waters.

Note: NAVTRAMETOCFAC does not set non-tropical weather warnings for Sub-Region CHARLIE Area C4. NAVTRAMETOC DET Meridian is responsible for setting warnings for all military activities within Area C4.

4. Weather Warnings.

a. Thunderstorm Condition II (T2) is set when thunderstorms are probable or expected within a twenty-five (25) nm radius or in 6 hours with winds less than 50 knots and hail less than ¾ inch.

b. Thunderstorm Condition I (T1) is set when thunderstorms are within 10 nm and/or are expected to influence the Naval Complex or Activity--normally within 1 hour--with winds less than 50 knots and hail less than ¾ inch.

c. Severe Thunderstorm Condition II is set when conditions are favorable for the formation of tornadoes and funnel clouds (to include waterspouts for coastal stations), and/or thunderstorms with winds greater than 50 knots, and/or ¾" hail, within 25 nm or 6 hours.

d. Severe Thunderstorm Condition I is set when a tornado or funnel cloud (to include waterspouts for coastal stations) and/or thunderstorms with winds greater than 50 knots and/or ¾" hail has been sighted or reported on radar within 10 nm, and will affect the Naval Complex or Activity (normally within 1 hour).

e. Freeze Warning Condition II is issued when temperatures less than 32 degrees F. are forecast for a duration of less than 12 hours.

f. Freeze Warning Condition I is issued when temperatures of less than 32 degrees F. are forecast for a duration of more than 12 hours.

B. Chief of Naval Air Training (CNATRA)

1. CNATRA has tasked radar-equipped NAVMETOCCOM activities co-located with CNATRA Air Wings to provide CNATRA Aviation Weather Warnings (CAWW) for specific phenomena occurring within 100 nm of the radar site. A CAWW will be issued when the National Weather Service Weather Warnings (WWs) or SIGMETs are not in effect for the area concerned and any of the following conditions exist:

Embedded thunderstorms
Severe thunderstorms with wind gusts of 50 knots or greater and/or hail ¾" diameter or more

CAWWs are issued for existing conditions; they are not forecasts.

2. A CAWW restricts all training flight operations within the geographic boundary of the warning area. Flight restrictions within a CAWW are the same as flight restrictions imposed by NATOPS for flights into or through a WW area.

C. Commander, Training Wing SIX (COMTRAWING SIX)

1. NAVTRAMETOCFAC provides advisory information on all hurricane positions and movements within the Gulf of Mexico and all associated weather activity or phenomena that could affect weather conditions in the Pensacola area and along Hurricane Evacuation (HUREVAC) Routes. The CO or HDO will provide recommendations concerning the setting or cancellation of HUREVAC conditions to COMTRAWING SIX.

2. NAVTRAMETOCFAC will provide support briefs to all squadrons subject to HUREVAC.Actual mass-departure briefs will be conducted utilizing the automated flight brief system.Designated personnel will provide pre-departure briefs.

D. NAS Pensacola

1.Forrest Sherman Field

a.Visual Meteorological Conditions (VMC) require ceilings and visibility of 1000'-3nm.

b.The Operations Duty Officer (ODO) will implement the Aircraft Wet Runway Recovery Bill when necessary.This requires all TRAWING SIX T-2C aircraft to make arrested landings.Criteria for implementing the Aircraft Wet Runway Recovery Bill include:

  Standing water on runway,
  Wet runway with a crosswind component that exceeds 15 knots, or
  Hydroplaning/poor braking action experienced during normal landing.

2.At NAS Pensacola Weapons Division, all magazines are closed and ordnance issuing is suspended when T1 is set.

3.NAS Pensacola Contract Fuel Branch discontinues fuel handling operations when electrical storms are within 5 miles of the field. The NAVTRAMETOCFAC FDO monitors the NEXRAD and LPATS located within the operational spaces.Together, these systems provide accurate lightning strike direction and distance information and are superb tools for determining fueling operations recommendations for the ODO.The ODO determines when fueling operations will commence or cease.

4.NAS Pensacola Port Operations Division, unless ordered by the Air Operations Officer or higher authority, shall dispatch no boat from the boat basin when Small Craft Warnings are in effect (NASPINST 9820.1).Additionally, Small Craft Warnings stop all Sea Survival Training.

5.The NAS Pensacola Recreation Department is greatly affected by T1, since it will close most outdoor activities, especially the swimming pools and beach areas.Small Craft, Gale or Storm Warnings, stop all boating at both the Sailing Facility and Sherman Cove Marina.

E.Supervisor of Naval Shipbuilding and Repair (SUPSHIP), Ingalls Shipyard, Pascagoula, Mississippi.Sustained or gusty winds in excess of 30 knots from any direction is a critical factor affecting shipyard operations.Large cranes are secured with winds of this speed, and personnel working aloft on masts or superstructures are also secured.At any given time, SUPSHIP has numerous ships in various stages of construction.High winds, heavy precipitation, thunderstorms, and widespread fog present both an operational and public relations problem.Newer classes of LHDs and DDGs are routinely constructed at Ingalls Shipyard.The FDO must remain cognizant of SUPSHIP operations, and be prepared to provide any type offorecast to support the shipyard.

F.Seabee Center, Gulfport

1.The Seabee Center located at Gulfport, Mississippi is a major hub for deployable Seabee units.Its location along the Gulf Coast assures essentially the same weather as can be expected at Pensacola.

2.Located with-in the sub-region Area C-1, Seabee Center, Gulfport is a recipient of Severe Thunderstorm and High Wind warnings issued for Area C-1..

G.NAVSURFWARCEN, Coastal Systems Station (CSS), Panama City, Florida.Thunderstorm activity affects CSS operations, since lightning in the Gulf of Mexico Operating Area greatly affects Mine Warfare Operational Evaluations (OPEVALs).In many cases a highly electrically-conductive cable is trailing from the helicopter to a towed vehicle in the water, and a lightning strike could cause significant equipment damage. Located in CNET Sub-region C3, CSS Panama City, is notified when Severe Thunderstorm warnings are issued for CNET Area C-3.

H.NAVSTA Pascagoula.Warning support for this Naval complex is expanding due to the increased presence of surface combatant ships homeported there.Pascagoula is supported by many different methods, including the Daily CHARLIE Area Forecast/Heavy Weather Advisories, telephone notification of severe weather, and by the NAVTRAMETOCFAC web site which provides the NAVSTA Pascagoula 72 hour forecast, near-real-time NEXRAD radar data, satellite pictures, tropical cyclone information, astronomical data and other weather charts.

I.COMNAVMETOCCOM.Located within the Sub-Region Area C1, this activity is a recipient of all tailored weather products that are issued for that CHARLIE Area.
