Red Flag Warning In Effect; JRWeather To Close April 17th

Red Flag Warning In Effect; No Outdoor Burning Allowed...

     PLEASE VIEW PREVIOUS POST AFTER VIEWING THIS POST, FOR MORE INFORMATION ON THE CLOSING OF THE JRWEATHER BLOG. Thanks.

This discussion is very similiar to previous post.

DISCUSSION
     Dangerously dry, and windy conditions have resulted in the issuance of a Red Flag Warning from the National Weather Service in Burlington, VT. For nearly the entire state of Vermont (excluding Bennington, and Windham Counties), and the Champlain Valley of Northern New York.

     Part of the criteria for a Fire Weather Watch or Red Flag Warning for pre-greenup (late winter-early spring) is a quarter inch or less of precipitation in the previous 3 days. This has clearly been the case for our region, as the last widespread measurable precipitation was back on the 8th which was 5 days ago, but that was generally less then a quarter of an inch, except across far eastern/ northeastern Vermont, where over a half inch of rain was reported with isolated areas with over an inch. With that in mind I don't feel the Northeast Kingdom (NEK) is needed under the Red Flag Warning, as too much rain in that area, plus some snow still on the ground across that area will help eliminate the fire threat, regardless of any other factors.

     The next factor for the region (Minus NEK) is winds will be strong. Winds will be sustained in the 10-20MPH range, with gusts up to 35MPH, especially in the North-South oriented valleys, such as the Champlain Valley, and lower Connecticut River Valley. In addition relative humidities will be very low, ranging from 18-25% from around noontime, until 6PM. Once the sun sets, relative humidities will rise rapidly, eliminating the fire threat.

     All these factors combined will result in the potential for rapid, and erratic fire growth should fires develop. A Red Flag Warning have been issued so you should not be burning at all. If you decide to disobey your local communities burn policies, and the Red Flag Warning by burning, it could result in not only a devastating fire, but subsequent legal penalties as well. Remember to contact your local fire warden, or fire officials before burning on any day. Stay tuned for further updates.

I apologize for no alert maps being issued. All JRWeather graphics are undergoing maintenance, as they are being transformed for the new Champlain Valley Weather blog site. Sorry for any inconvenience.
