SOUTHEAST TEXAS FORECAST DISCUSSION

958 AM CDT FRI AUG 15 2003

TROPICAL STORM ERIKA CHUGGING WEST AT FAST PACE...ALONG 26 DEGREES
NORTH. SEE LATEST TPC ADVISORIES. FEEDER BAND ABOUT 120NM SOUTHEAST OF
GALVESTON AND SHOULD SEE THIS BAND REACH THE 20-60 NM AROUND 18Z. SCA
UP FOR THE 20-60NM WATERS AND WILL BE WORDING THIS AS 25-30 KNOTS WITH
HIGHER GUSTS IN SQUALLS. SUSTAINED WINDS ALONG THE IMMEDIATE COAST
SHOULD REACH 15 TO 20 MPH AROUND 2 PM. WILL BE MAKING A FEW MINOR
TWEAKS TO THE COASTAL ZONES...OTHERWISE THE PACKAGE LOOKS GREAT.

I got the drift that we might get some rain and wind from Erika. That's no biggie at all. Just trying to understand what they're talking about with "20-60NM" and "SCA."

If it's 120NM from us now, what with the range of "20-60?" Obviously, I don't have a clue what they mean by that.

Thanks in advance!

SCA means SMALL CRAFT ADVISORY I believe and I think they just mean that the feeder band that was located 120NM south of Galveston will reach 20-60NM south of Galveston at 18Z.

I bet you already knew that...

Oh, doh...small craft advisory. Racked my brain but couldn't pull that one out of the clouds. As for the 20-60NM, it just didn't read right for my brain to decipher.

Thanks, Colin!

Well, up here, they use SCA for 2 different things. SCA TSRA WILL DVLP ACROSS THE RGIN TODAY. That statement would obviously mean that SCA is Scattered. The above statement, like Colin addressed, would mean that it is a Small Craft Advisory. I think NM means Nautical Miles, even though I didn't understand that. 18Z is 1 P.M. CDT, if you didn't already know that ( which I think you do ).
Reading AFD's can be interesting, and sometimes funny. When LOT gets in it's humorous stage, it will say how corn will affect the SVR potential...and they made this statement last month. "NO MORE RAIN IN THE FORECAST....FOR REAL THIS TIME". Well I am sure glad they are "for real" when they forecast. lol.
