"Explosive Cyclogenesis" Wow...that sounds very scary. I wonder what that exactly means in terms of weather on the ground/walking conditions.
if this does happen
any person out walking in hilly terrain needs to avoid doing so, the effect will be rapid pressure drop,very high winds making it uncomfortable to walk properly. if on a elevated position. such as the border crossing from France into Spain high risk of exposure..
in rural areas with many old building in fragile states there is a risk or debris flying around....winds can reach over 70 mph ...
avoiding forested areas due to risk of falling trees ...
