Grear idea!
However, while leaning on the safe side may be good, it does seem a little overly cautious at the moment.
The site is currently showing YBTL as
Extreme IFR.
Current METAR is:
TTF METAR YBTL 160200Z 03007KT 9999 FEW020 SCT240 OVC300 FEW024TCU 30/23 Q1000
RMK RF00.0/000.2 DIST SH
INTER 0300/0500 3000 SHOWERS OF RAIN BKN015
Based on visual observation I would class the airspace immediately around YBTL at the moment (12:22 local time) as
VMC or
Marginal VMC at worst.

PS: Is the 2500' ceiling too cautious?
