SUDDEN ONSET Warning refers to arrangements to rapidly disseminate information concerning imminent disaster threats to government officials, institutions and the population at large in the areas at immediate risk. These warnings normally relate to tropical storms and floods.

SLOW ONSET Early warning is the term used regarding slow-onset disasters, especially famine. Early warning activities include the process of monitoring the situation in communities or areas known to be particularly vulnerable to the effects of droughts, crop failures and/or changes in economic conditions. An adequate warning will enable remedial measures to be initiated before hardships become acute. Early warning is a disaster response activity only if it has failed to detect the warning signs or where such signs were ignored.
