survival kit

at dawn this day.. i was awake not able to sleep because of the heavy rain, usually when we have weather like this.. it is not as bad as this one... since we are not always hit by the typhoon unlike in the northern part of the country.. except now, we are experiencing heavier rains than the usual, it made me think i should be keeping a survival kit. i was awake at 3am when the lights went off too.. good thing i always keep candles in stock and some matches too as the rechargeable lights, all four of them ran out of energy too! i guess out of gut feeling too i went and check my kid's medicines if i have those in stock as well..and yes i do not have the ones for asthma anymore.. so when hubby woke up i told him i will be buying stuff for the kit..like medicines, some betadine, band aids, can goods, more candles and an extra rechargeable light. we never know when calamity would strike again and from the look of the sky today, it is still going bad... anyone here have a survival kit at home? what are the things inside it? i might learn something too as i will be going to buy some later.
