Subject: Re: How NOT to do an Amber alert...

In another case today at 5:10pm we were hit by a Tornado in Jupiter and
Rivera Beach Fla. A VERY rare instance since the touchdown sites were from
2 blocks to 2 miles from the beach, this does not normally happen. Initial
reports are a F1 and the NWS may upgrade that to a F2 after studying the
damage in the morning.
No alerts were sent out at all, before or after the strikes. Alerts are a
nice idea and may work in some instances but we must not think of them as
something that can be depended on. The only reports that were received were
from the local TV stations when people started e-mailing photos and calling
in that they had video. Once they put the word out then everyone "noticed".

Only if the position packet CHANGES. If you put PHGr in one and only PHG
at a different rate in another one, then they will always appear
different and each one will be treated as a changes position and the
operator alerted with the "N" in CW...

No, the one exception to the changed position packet is a Weather packet
where only the TEMP, and rain are checked for a change and the WIND is
only checked for a change over threshold. But if TEMP changes or rain,
then the operater hears the "N" on that station.
