THUNDERSNOW, WHILE RELATIVELY RARE ANYWHERE IS MORE COMMON WITH LAKE-EFFECT SNOW IN THE GREAT LAKES AREA OF THE UNITED STATES OR CANADA, THE MIDWESTERN U.S., AND THE GREAAT SALT LAKE....THUNDERSNOW OFTEN PRODUCES SNOWFALL RATES IN THE RANGE OF 2 TO 4 INCHES PER HOUR...SNOWFALL OF THIS INTENSITY MAY LIMIT VISIBILITIES SEVERELY, EVEN EVEN DURING LIGHT WIND CONDITIONS....HOWEVER, THUNDERSNOW IS OFTEN PART OF A SEVERE WINTER STORM OR BLIZZARD....WINDS OF ABOVE OR TROPICAL STORM FORCE ARE FREQUENT WITH THUNDERSTORMS...AS A RESULT VISIBILITIES IN THUNDERSNOW ARE FREQUENTLY UNDER 1/4 MILE....ADDITIONALLY, SUCH WIND CREATES EXTREME WIND CHILLS AND MAY RESULT IN FROSTBITE.

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.
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.
A Severe Thunderstorm Watch means that conditions are favorable for the development of severe thunderstorms in and close to the watch area. Watches are usually in effect for several hours with 6 hours being the most common.
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.
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.
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.
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.
A Flood Advisory means river or stream flows are elevated or ponding of water in urban or other areas is occurring or imminent.
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.
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.
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. Never allow children to play in or near flood waters. Stay tuned to NOAA weather radio or local media for further statements and updated forecasts.
Is issued when sustained windss are forecast to be 31 to 39 mph or gusts will range between 46 and 57 mph. Winds of these magnitudes may casue minor property damage without extra precautions.. Motorists in high profile vehicles should use caution until the winds subside.
A High Wind Watch means the potential exists for strong damaging winds to develop. These strong winds could bring down trees and power lines as well as cause property damage. Stay tuned to Weather Radio or the other radio and TV stations for further details or possible warnings.
A High Wind Warning is issued when sustained winds of 40MPH are expected for at least an hour, with gusts of 58MPH or greater at any time. Damage to trees...power lines and property are possible winds of this magnitude. If you have a high profile vehicle, be careful until the wind subsides.
A Tornado Watch means that conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening conditions and listen for later statements and possible warnings.
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. If no shelter is available...lie flat in the nearest ditch or low spot and cover your head with your hands...If driving, do not seek shelter under a highway underpass. Be sure to stay tuned to NOAA Weather Radio or your favorite weather source for further updates.
Is issued when dense fog will substantially reduce visibilities resulting in hazardous driving conditions in some areas. Motorists are advised to use caution and slow down as objects on and near roadways will be seen only at close range. Stayed tuned to NOAA Weather Radio or other radio and TV stations for further details or updates.
Is issued when frost is expected to develop during the growing season. Those with agricultural interest in the warned area are advised to protect tender vegetation. Also, potted plants that have been placed outdoors should be covered or brought inside away from the cold.
A Freeze Watch means sub-freezing temperatures are possible. These conditions could kill crops and other sensitive vegetation. People need to monitor later forecasts.
A Freeze Warning is issued when freezing temps are forecast to threaten outdoor plants. If you are in the warned area you should protect tender vegetation. Also potted plants normally left outdoors should be covered or brought inside away from the cold. "Killing" may be used during the growing season when the temperature is expected to be low enough for a sufficient duration to kill all but the hardiest herbaceous crops.Stay tuned to NOAA Weather Radio or TV stations for further details or updates.

A WARNING IS TYPICALLY ISSUED 36 HOURS BEFORE THE ANTICIPATED FIRST OCCURRENCE OF TROPICAL-STORM-FORCE WINDS...CONDITIONS THAT MAKE OUTSIDE PREPARATIONS DIFFICULT OR DANGEROUS. PREPARATIONS TO PROTECT LIFE AND PROPERTY SHOULD BE RUSHED TO COMPLETION.
Beach Hazards Statement
A BEACH HAZARDS STATEMENT IS ISSUED WHEN SWIMMING RISKS EXIST FROM A COMBINATION OF WIND AND LARGE WAVES INCLUDING RIP CURRENTS AND LONGSHORE CURRENTS. THESE SWIMMING RISKS CAN CREATE LIFE-THREATENING CONDITIONS EVEN FOR GOOD SWIMMERS. FOLLOW THE INSTRUCTION OF LOCAL AUTHORITIES OR STAY OUT OF THE WATER.
Low Water Advisory
A LOW WATER ADVISORY MEANS WATER LEVELS ARE EXPECTED TO BE BELOW THE CRITICAL MARK FOR SAFE NAVIGATION. VESSELS MAY BOTTOM OUT OR BECOME GROUNDED. CONTACT THE COAST GUARD FOR THE LATEST WATER LEVEL. MARINERS SHOULD USE EXTREME CAUTION OR CONSIDER WAITING UNTIL WATER LEVELS RISE.
Small Craft Advisory
A SMALL CRAFT ADVISORY MEANS THAT WAVES WILL AVERAGE 4 FEET OR MORE AND WIND SPEEDS MAY EXCEED 22 KNOTS WHICH WILL CREATE HAZARDOUS CONDITIONS TO SMALL CRAFT. INEXPERIENCED MARINERS...ESPECIALLY THOSE OPERATING SMALLER VESSELS...SHOULD STAY IN PORT OR RETURN TO PORT PRIOR TO THE ONSET OF THESE CONDITIONS.
