Summer Advisories

Heat

Excessive Heat Advisory

An Excessive Heat Advisory means that a period of high temps is expected. The combination of high temps and high humidity will combine to create a situation in which heat illnesses are possible. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun & check up on relatives and neighbors.

Excessive Heat Warning

An Excessive Heat Warning means that a prolonged period of dangerously hot temps will occur. The combination of hot temps & high humidity will combine to create a dangerous situation in which heat-related illnesses are likely. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun & check up on relatives and neighbors.Temperatures within vehicles can become lethal in a few minutes. Never leave children or pets in vehicles. Remeber to beat the heat...Check the back seat.

Severe Thunderstorm Warning

Is issued when either a severe thunderstorm is indicated by the WSR-88D radar or a spotter reports a thunderstorm producing hail one inch or larger in diameter and/or winds equal or exceed 58 miles an hour; therefore, people in the affected area should seek safe shelter immediately. Severe thunderstorms can produce tornadoes with little or no advance warning. Lightning frequency is NOT a criteria for issuing a severe thunderstorm warning. They are usually issued for a duration of one hour. They can be issued without a Severe Thunderstorm Watch being already in effect. Severe thunderstorms can result in loss of life and/or property. Information in this warning area includes:

  • Where the storm was
  • What towns will be affected
  • Primary threat associated with the storm.

Flood

Flash Flood Watch

A Flash Flood Watch means the threat of flash flooding exists along rivers and creeks. If you are in the watch area you should monitor weather conditions closely. Be ready to move to higher ground if flooding is observed or a warning is issued. Stay tuned to weather radio or other radio and TV stations for further updates.

Flash Flood Warning

A Flash Flood Warning signifies a dangerous situation where rapid flooding of rivers, small streams, or urban area is imminent or is occurring. Very heavy rain that falls in a short time period can lead to flash flooding depending on local terrain, ground cover, degree of urbanization, degree of man-made changes to river banks, and initial ground or river condition.

Urban and Small Stream Advisory

An Urban and Small Stream Advisory alerts the public to flooding which is generally only an inconvenience (not life threatening) to those living in the affected area. Issued when heavy rain will cause flooding of streets and low-lying places in urban areas. Also used if small rural or urban streams are expected to reach or exceed bankfull. Some damage to homes and roads could occur.

Flood Advisory

A Flood Advisory means river or stream flows are elevated or ponding of water in urban or other areas is occurring or imminent.

Flood Watch

A Flood Watch means there is a potential for flooding based on forecasts. You should monitor local forecasts and be alert for posible flood warnings. Those areas prone to flooding should be prepared to take action should flooding develop.

Areal Flood Warning

An Areal Flood Warning is issued for highflow, overflow or inundation of a defined area, or when creeks and non-mainstream rivers are expected to flood or remain in flood after 6 hours and there is a threat to life or property and possible evacuations.

Flood Warning

A Flood Warning means flooding conditions are imminent or occurring in and around the warning area. Never drive vehicles through flooded areas. The water may be too deep to allow safe passage.

Tornado Warning

Is issued when strong rotation has been detected in the storm and atmospheric conditions support that rotation reaching the ground...A tornado may already be on the ground or is expected to develop shortly. The safest place to be during a tornado is in a basement. Get under a workbench or other piece of sturdy furniture. If no basement is available...seek shelter on the lowest floor of the building in an interior hallway or room such as a closet..Use pillows or blankets to cover your body and always stay away from windows. If in a mobile home or a vehicle, evacuate them and get inside a substantial shelter.
