Post subject:  Question about a remark in a METAR report

Hi Everyone,

I've noticed the abbreviation "ACSL" followed by directions in the remarks section of a number of METAR reports, but I'm not sure what it means. Here's an example of how it appears:

KBAB 052355Z 17016KT 10SM FEW120 BKN250 28/03 A2982 RMK ACSL NE-E SLP099 ESTMD SLP 56010

Anyone here have an idea as to what this abbreviation means?

Thanks in advance!
Marc
