My very first day of flagging ever happened to fall on a day when the remnants of a hurricane blew through Lime Rock Park. The gentleman who was training me asked me at the end of the day what I thought of flagging, and I told him I loved it. He laughed, and said “If you loved in this conditions, you’re really going to love it under normal circumstances”.
I thought of this on Friday of the Thompson Majors event, as hurricane Elsa was due to come up the coast and overspread Thompson with heavy rains. And heavy rains it had in spades, as the track quickly was overcome with standing water. By the second session of Friday morning’s practice and qualifying, a lake formed at the station just before mine, and we watched in amazement as cars would come through on their first laps, not knowing the lake was there, only to dive for the apex and cause splashes towering 8ft in the air, and the race car visibly slowing down as they hit a wall of water. Action was suspended, and a waiting game then played out as we tried to wish the rain away. As us flaggers sat in the garages, deadlines of 11am, noon, and 1pm came and went. Finally at 2pm, they decided that there were too many spots on track that would not drain in time even if the rain stopped (which it did), so a consolidated schedule focused on Saturday were put in place. When we took advantage of the rain stopping, our visuals on the track revealed Pit In lane had about 6-8″ of standing water in it, a small river of about 3-4″ of water was flowing across the front straight just up from the starter stand, the lake at Turn 3 that was very deep, and smaller rivers running across the track before and after the hairpin at Turn 4 (my station).
Saturday dawned cloudy but rain-free. However, there was a lot of water still draining from the area surrounding the track. Track services at Thompson was out trying to dig some minor trenches in the grass to help reroute water drainage at the braking zone just before the bridge at turn 5. Cars handled the wet spots on track with pretty good strategies, but we still had some cars running off track due to water in key braking and turning zones. One Spec Miata entrant put down 3 of 4 pairs of skid marks that led directly at the armcom on driver’s right at the turn under the bridge. Some more trench digging by track services finally allowed that spot to dry up, and drivers didn’t have many issues in any of the wet spots after that.
NER has a great write-up with spectacular pics and video of the challenges from that event.
