Common Topics
- How do I get information about past weather data?
- If you are looking for occurrences within the past year or two then you can access the information on our website under the "Climate" section. Click on Local. This will give you access to several products for several locations with information concerning temperature, rainfall amounts, days it rained, winds, heating & cooling degree days and more. The "CF6" and "CLI" products are the most frequently used. Want more locations? Want to dig deeper? Select the "NOWData" tab. If you need information that is not on that page, or is older than a couple of years then you can search the National Climatic Data Center's web page or the office of the Georgia State Climatologist's web page.
- Where can I find information on Lake and River Levels and forecasts?
- Look for a link called "Lakes & Rivers" on the blue navigation bar on the left side or our web pages.
If you need further information, you might be able to find it at the Southeast River Forecast Center web page, or the USGS, or U.S. Army Corps of Engineers.
- Where can I find information about sunrise, sunset and moon phase?
- Look for a heading called "Miscellaneous" on the blue navigation bar on the left side or our web pages. Click on Sunrise/Sunset. On that page is a link to the US Naval Observatory where you will find dates and times for eclipses and changes of season.
- Where can I find information on ozone levels for the State of Georgia?
- The Department of Natural Resources has a web site that will provide this information.
If you are looking for historical information, try http://167.193.59.200/amp/amp_query.html also from the GA DNR.
- Where can I find information on Heating and Cooling Degree Days?
- Take a look at our "degree day" page. You will find a definition for the term "degree day" along
with daily values over the past year at Atlanta, Athens, Columbus or Macon.
- Where can I find real time RADAR images?
- On all NOAA/NWS websites the radar images are "real time" (the same images our meteorologists are looking at) unless there
is a problem beyond our control due to problems on the internet or on web servers. On the Peachtree City website radar data for North and Central
Georgia can be obtained by clicking on the links under "Radar Imagery" in the navigation bar on the left side of every page.
- What is a "Severe" Thunderstorm?
- The National Weather Service classifies a severe thunderstorm as a storm that has winds greater than or equal to 58 miles per hour and/or hail 3/4 of an inch (penny-size) in diameter or larger. Hail size is determined by the largest size observed, not an average or mean. Lightning does not factor into the designation of a severe thunderstorm warning at this time.
General Information about Our Office
- Does the Peachtree City NWS provide services to the entire state of Georgia?
- No. Some southern and eastern counties are served by neighboring NWS offices.
This is due to the proximity of these other offices to the areas they cover.
This helps to give a more accurate coverage for all areas. The other offices that cover
counties in the state are in Greenville-Spartanburg, Columbia, Charleston, Jacksonville,
and Tallahassee. Links to these offices can be found on our home page.
- Do you give tours through your facility? If so where can I find information about booking one?
- Yes. Information on scheduling tours and directions to the office can be found at http://www.srh.noaa.gov/ffc/html/tours.shtml.
Also keep a look out on the website as the NWS PTC office does have Open House from time to time and it is advertised on our web site!
- Where can I find information about NOAA weather radio?
- The navigation bar on the left side of our web pages has link called NOAA Weather Radio. Following that link will take you to a page that gives the frequencies and the SAME codes for the correct programming of your weather radio... and a lot of other information about NWR.
- When is Severe Weather Awareness Week?
- Our "Severe Weather Awareness Week" is usually the first full week in February.
Specific Questions about Meteorology
- What do the acronyms often seen in forecast discussions (such as "MCS" or "CAD") mean? Where can I decode these?
- You can find the meaning of many acronyms and abbreviations often used in our products at the National Weather Service glossary page.
- Why are nighttime temperatures often much warmer in Atlanta than elsewhere in North GA?
- The temperature is taken at Hartsfield-Jackson International Airport which is affected
by a phenomenon known as the "Urban Heat Island". On relatively calm, clear nights
temperatures in urban areas are affected by the concentration of concrete/ashpalt, and
also human activity. Concrete and ashpalt tends to retain heat through the night, while
more grassy, or otherwise vegetated areas cool off. Activity related to humans, such
as operating automobiles and aircraft generates heat and also stirs the air, which interferes
with the nighttime cooling process. So...compared to areas less urbanized than Atlanta,
temperatures on clear, calm nights will be warmer in Atlanta than in the areas outside the
perimeter and across the rest of North Georgia.
- Why is Rome's temperature generally warmer than surrounding areas?
- There is nothing wrong with the thermometer. It has been checked several times.
That observation is taken at the Rome Airport and there is a bit of a microclimate
there. The location is nearly surrounded by higher terrain -- it is in a geographical feature called a "proverbial bowl". When air flows up and over higher terrain and then down into lower areas during the daylight hours, it warms up. Rome is located in a lower area surrounded by higher terrain.
