Much was accomplished during the month of March. Training sessions were conducted on net operations and how to be an effective net control station (NCS). Jim Butch from the NWS in Jackson, Billy Bob Sekul from the Jackson ARC SKYWARN Center, and Malcolm, W5XX, the ARRL Section Manager for Mississippi was here on the 25th for the Storm Spotter class. The turnout was very good for all of these programs and over half the storm spotter class were HAMs or their guests. The emergency net was also activated twice during the month for severe thunderstorms moving through our area. The nets went very well. I received comments from several sources outside the amateur community about how professional you sounded. Thanks. SPOTTER TIPS - What to report: tornadoes funnel clouds coastal flooding unusually high surf rotating wall clouds damaging thunderstorm winds persistent heavy rains/floods large hail snow depth/ice accumulation any weather phenomena causing death or serious injury your call or other ID where & when the event occurred (reference landmark or city) damage or injuries MPH INDICATIONS 25-30 large branches moving; whistling heard in wires. 30-40 whole trees moving; inconvenience in walking against wind. 40-45 breaks twigs and small branches, impedes walking. 45-55 larger branches and weak limbs may break; slight structural damage occurs. 55-65 moderate structural and tree damage. > 65 heavy to severe structural and tree damage.
SAFETY FACTS: Tornadoes in our area usually move in a southwest to northeast direction. If it appears to be standing still it may be moving directly toward you. The largest hail generally falls just preceding the tornado. Report the size of the largest hailstones. Use a ruler or the following as a reference. 1/4" is pea size, 1/2" inch is marble (from NOAA guide), 3/4" is dime, 1" is quarter, 1-3/4" is golf ball, 2-3/4" is baseball. When reporting wind speeds or gusts, tell whether they are measured or estimated. the modified Beaufort Scale below will help you estimate speeds. OTHER NOTES:
