7.0 Description of Area

The Pittsburgh CWA is located in the northeast portion of the continental United States with an area of about 19,000 square miles. The topography ranges from rolling hills with farmland over the south and west portions to mountains in the north and east. The Allegheny Mountains extend along the eastern boundary of the CWA with elevations as high as 4,000 feet in West Virginia and Maryland . Considerable agricultural land lies in the rolling hills and mountain valleys. Hardwood forests provide the majority of the vegetative coverage in the higher elevations. The growing season averages about 166 days in length; extending from late April to mid October.

8.0 Fire Season

WFO Pittsburgh will issue a daily fire weather forecast (PITFWFPIT) for the Pittsburgh CWA during the entire year.

11.0 Spot (non-routine) Forecasts

The spot forecast is a site-specific, localized weather forecast available for wildfire support. This forecast will include wind, temperature, humidity, and smoke dispersion (mixing height/mixing winds) forecasts. It will normally cover a 12 to 36 hour period and will be issued upon request by the agency overseeing the wildfire. Spot forecasts will only be issued for prescribed or planned burns requested by federal and state agencies.

11.1 Requesting the Issuance of a Spot Forecast

a) Completion of form WS Form D-1 by the requesting agency which will provide current weather information for the site-specific location.

{See attachment # 11 }

b) Agency will provide the following information:

1) Agency Name

2) Location and Size of the wildfire {Latitude and Longitude)

3) Elevation, Geography and Topography

4) Recent weather observation

5) Any additional information that would help the forecaster

There are 2 ways to make a request for a spot forecast.

1. Make a request through the national NWS SPOT internet program (MUCH PREFERRED).

a) Agency will access the NWS SPOT internet site via a link from the Pittsburgh internet site.

b) After accessing the NWS SPOT web site, the agency will complete the request form providing all available information for the spot forecast request. The same information listed on the WS Form D-1.

c) After submitting the request, a product will alarm at the WFO PBZ office.

d) After receiving the alarm, the forecaster will create a spot forecast then go to the internet site and enter

it. The program will also create a PITFWSPBZ and issue that.

e) The agency can then obtain the spot forecast from the same internet site.

2. Make a request by calling or faxing the request directly to our office.

a) Agency will call or fax the information from the WS Form D-1.

b) Forecaster will create the spot forecast then issue it through the internet.

c) The agency can obtain it through the internet or by providing an appropriate phone or fax number.

11.2 Spot Forecast Product{See attachment # 8}

The duty forecaster will provide the following information in the spot forecast product:

a) Time period for the forecast (12-36 hours)

b) A brief synopsis…including any warnings or watches in effect.

c) Sky/Weather

d) Temperature forecast (maximum T for the day, minimum T at night)

e) Relative humidity forecast (minimum RH for the day, maximum RH at night)

f) 20 foot forecast wind direction and speed (indicate height if not the 20 foot wind)

g) Probability of precipitation

h) Any other weather phenomena deemed important by the duty forecaster including

any warnings, watches or advisories in effect for the area.

i) For the first 12 hours...a matrix is available giving two hour increments of sky cover, weather type/coverage, temperature, RH, 20 foot sustained wind, and 20 foot wind gust.

12.0 Fire Danger Ratings {See attachment # 10}

Due to the non-meteorological parameters involved in forecasting fire danger ratings, the direct computation of fire categories will be calculated in season by the Bureau of Forestry. When a category of VERY HIGH or EXTREME is calculated, PBZ should be notified. State/federal agencies may request PBZ to issue a Special Weather Statement (SPS) highlighting the threat.

13.0 Fire Weather Watches and Red Flag Warnings ( PITRFWPBZ ) {See attachment 9 }

A FIRE WEATHER WATCH is issued to alert the user to the possible development of a Red Flag event in the near future. This could be up to 72 hours in advance.

A RED FLAG WARNING is issued to warn the user of an impending or on-going Red Flag event. A Red Flag Warning will be issued immediately when Red Flag conditions are occurring or for impending Red Flag conditions when there is a high degree of confidence that conditions will develop within the next 6 hours.

Specific conditions must be met for a Fire Weather Watch and/or a Red Flag Warning to be issued. These conditions are as follows:

For PA...
- Relative Humidity less than or equal to 30%
- Sustained Wind Speed greater than or equal to 15 mph
- 10-hour Fuel Stick Moisture less than or equal to 15%

For MD...
- Relative Humidity less than or equal to 30%
- Sustained Wind Speed greater than or equal to 20 mph
- 10-hour Fuel Stick Moisture less than or equal to 8%

For WV/OH...
- Relative Humidity less than or equal to 25%
- Sustained Wind Speed greater than or equal to 15 mph
- 10-hour Fuel Stick Moisture less than or equal to 8%

The appropriate district forestry office should notify the Pittsburgh WFO when the fuel moisture of the 10 hour fuel moisture sticks have/or are expected to drop critical values.

Fuel values can also be obtained at the Wildland Fire Assessment System (WFAS) web page at

http://www.wfas.net/index.php/dead-fuel-moisture-moisture--drought-38

If, after being notified of low fuel moisture, the Pittsburgh WFO determines that the relative humidity/wind criteria may (or will) be met, the Pittsburgh WFO should coordinate (when possible) with the affected forestry district(s) and decide whether a FIRE WEATHER WATCH or RED FLAG WARNING is needed. If contacts cannot be made to coordinate, the Pittsburgh WFO may issue a FIRE WEATHER WATCH or RED FLAG WARNING based on meteorological conditions and a reasonable estimate of fuel conditions.

If a Fire Weather Watch or Red Flag Warning is issued, the Pittsburgh WFO will include a HEADLINE in the daily fire weather forecast, as well as any spot forecasts issued during the event. In addition, if a Fire Weather Watch or Red Flag Warning is issued after the routine Fire Weather Forecast is issued, an updated FWF shall be issued.

For events that are approaching, but less than Red Flag criteria, Special Weather Statements should be issued highlighting the threat.

14.0 NOAA Weather Radio

The NOAA (National Oceanic and Atmospheric Administration) weather radio continually broadcasts weather and related information over a special broadcast band. This band is available on specially designed radios equipped to pick up the frequencies assigned to this band. Maps of the areas covered by the PBZ CWA radios are included.

{See attachments # 12 through 20 }

Following are the PBZ CWA NOAA weather radios and their assigned frequencies.

Location Station Frequency

a) Pittsburgh, Pa KIH-35 162.550

b) Parker, Pa WWG-53 162.425

c) Bridgeport, Oh WWF-35 162.525

d) High Hill, Oh WXJ-47 162.475

e) Backbone Mountain , WvKXI-73 162.450

f) Morgantown , WvKWN-35 162.475

h) Punxsutawney, Pa KZZ-42 162.500

i) New Philadelphia, Oh WNG-735 162.425

15.0 On-Site Meteorological Support

Large wildfires may require an incident response. If the occasion should arise in the Pittsburgh CWA, then the appropriate state would request an Air Transportable Mobile Unit ( ATMU). This unit would be requested by the state or federal government through the U.S. Forest Service or the National Interagency Fire Center (NIFC) in Boise, Idaho . The local user agency requesting the on-site forecast service has the primary responsibility (administrative, financial, etc.) for transporting the ATMU and Incident Meteorologist to and from the incident.
