LL bring her in anyway if theres a storm brewing to be on the safe side, the undercarriage can drop (look thro her back legs) anything upto 10 days before, if you can get near her check the teats if they're hardening up she's not far away, if they're soft and supple she's some days off, nearer the time you'll get a touch of liquid from the teats but for the real test is the start of nest building, give her some bedding and if she takes it in her mouth instead of pawing it around she's not far away.
Hope the storms not too bad.
best of luck Mandy
