- Tornado Preparedness
- Education + personal preparedness
- warnings
- watch - potential to exist, warning - most likely to exist
- drills
- awareness weeks at schools
- normalised in tornado alley
- closer to internal walls
- cannot be done if outside or no internal walls
- awareness weeks at schools
- personal preparation
- weather ready - NOAA weather station + warnings
- notifications - FEMA app
- family evacuation plan
- different to hurricanes - less time
- safe room
- preparation safety kit
- unlikely to be useful with little warning + might not have it on you
- warnings
- Prediction
- mapping less important than for hurricanes
- tornadoes all over so can't forecast location/large map + can't help all vunerable
- not often + cover small area
- leads to complacency
- USA mapping
- better than Bangladesh
- 148 Doppler radars - can tell if dust flying up from ground
- but birds can interfere
- hook echo - can see if air + preciptation is curving into mescyclone
- mapping less important than for hurricanes
- Building design
- Building codes
- metal rather than wooden frames
- thicker windows
- triple hinged doors
- building codes better in UK than US
- Emergency shelters
- tornado alley - gyms, schools etc need shelter for up to 250mph winds
- underground shelter for 12+ people $30,000
- expensive
- Oklahoma 10,000 shelters, 400 govt built
- not many govt built
- Bangladesh - shelters for settlements not individuals
- low income + poor govt can't investment in building
- Building codes
- monitoring
- requires someone seeing tornado e.g. rotating wall cloud for 10-20 mins + beaver's tail - smooth flat cloud from Eastern edge to NE
- Education + personal preparedness
- evaluation
