Risk Overview
Providence County carries a medium composite natural disaster risk, with a National Risk Index score of 93.7 out of 100 — placing it in the 94th national percentile and near the national midpoint for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
The county's risk is driven primarily by heat wave (prolonged periods of extreme heat that threaten health and infrastructure) at High risk — $9M in expected annual loss and about 6.04 events per year; riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at High risk — $93M in expected annual loss and about 3.00 events per year; and hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Medium risk — $9M in expected annual loss and about 0.18 events per year. Across all hazards, FEMA estimates $130M in expected annual loss for a population of 660K.
Beyond physical exposure, Providence County has a medium social vulnerability rating (how susceptible the population is to harm) and a high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
History supports the rating: Providence County has received 25 federal disaster declarations since 1978, including 7 for severe storm events and 7 for snowstorm events. The most recent was Severe Storm and Flooding (severe storm), declared in March 2024.
Among 5 Rhode Island counties, Providence County ranks #1 for overall natural disaster risk.
