La Niña can also lead to a more severe hurricane season. La Niña causes the jet stream to move northward and to weaken over the eastern Pacific. During La Niña winters, the South sees warmer and drier conditions than usual.

Nuisance flooding can lead to road closures, overwhelmed storm water systems, damage to transportation infrastructure, and coastal erosion. Nearly 200,000 Californians live in low-lying coastal areas and 873 miles of coastal roads are at risk from flooding during King Tides, storms, and other periods of elevated sea level.

to withstand Category 4 hurricanes and deliver real-time storm data, including water levels and weather conditions, during severe coastal weather events. his information is critical

In the U.S., where over half of us live along the coast and more than 78 percent of our overseas trade by volume comes and goes along our marine highways, the health of our coasts is intricately connected to the health of our nation's economy. The National Ocean Service (NOS) translates science, tools, and services into action, to address threats to coastal areas such as climate …

June 8 is World Ocean Day — part of our annual recognition of National Ocean Month. Every day, each of us plays a role in addressing evolving economic, environmental, and social pressures on our ocean and coasts. This month is also our eighth year of NOS’s '30 Days of the Ocean' campaign. This online effort affords us the opportunity to share the importance of our world …

The Interagency Task Force on Sea Level Change co-develops critical science on sea level rise and its related impacts. This interactive site allows users to explore past, present, and projected future sea level rise, associated impacts, and adaptation measures for their area.
