Overview

The United States is grappling with severe weather events and seismic activity this week, with record-breaking flash flood warnings and tsunami alerts triggered by an 8.8-magnitude earthquake off Russia’s Kamchatka Peninsula on July 30, 2025. For Non-Resident Indians (NRIs) in the U.S., staying informed and prepared is critical. This report provides essential details on these events, their impacts, and safety tips for the Indian diaspora.

Flash Flood Warnings

Unprecedented Flood Alerts

In 2025, the U.S. recorded 3,040 flash flood warnings from January 1 to July 15, the highest since 1986, driven by intense rainfall and climate change, according to Iowa State University’s Iowa Environmental Mesonet. These events have impacted NRI communities in states like Texas, New York, and New Jersey.

Key Flash Flood Events

Central Texas (Hill Country): Early July floods in Kerrville caused the Guadalupe River to rise over 20 feet in 90 minutes, resulting in 120 deaths. NRIs in Texas should remain cautious, as the region continues to face flood risks.
New Mexico (Ruidoso): Flash floods in early July killed three people, damaging homes and businesses in this remote area.
New York City: This week, Central Park saw over 2 inches of rain in one hour, triggering flash flood warnings. Indian communities in NYC and New Jersey are advised to monitor local alerts.
Other Affected Areas: States like North Carolina, Illinois, and New Jersey have seen extreme rainfall, including four 1-in-1,000-year events earlier this month.

Impacts for NRIs

Flash floods pose risks to life, property, and infrastructure, particularly in urban areas with large Indian populations. NRIs are urged to avoid flooded areas, secure property, and stay updated via local news.

Recognize natural signs: a strong earthquake, sudden ocean changes, or loud ocean roars.
Use NOAA Weather Radio or the Emergency Alert System for updates.
Prepare a go bag and family communication plan, especially for NRIs in coastal areas.
