Hurricane Erin Continues to Impact the U.S. East Coast

Hurricane Erin, now a Category 2 hurricane, is located about 480 nautical miles west-southwest of Bermuda and is moving north-northwest.1 While the storm is not expected to make landfall on the U.S. East Coast, it is a large system that is creating significant hazards.2 Life-threatening surf and rip currents are expected along the East Coast from Florida to New York, and coastal flooding has already begun in parts of the Outer Banks in North Carolina.3 The National Hurricane Center (NHC) is cautioning beachgoers to stay out of the water.4

Developing Tropical Systems in the Atlantic

The NHC is also monitoring two other areas of interest in the Atlantic basin.5 A tropical wave over the central tropical Atlantic is producing a broad area of disorganized showers and thunderstorms, with environmental conditions appearing conducive for gradual development.6 A tropical depression could form later this week or over the weekend.7 Another tropical wave is located just off the coast of Africa, but its development is expected to be limited.

Dangerous Heat and Storms Across the U.S.

A dangerous heat wave is intensifying and expanding across the Southwest, with temperatures climbing into the 100s and 110s.8 Heat-related warnings and advisories are in effect for much of southern California and the Desert Southwest.9 Meanwhile, widely scattered thunderstorms with heavy downpours are forecast for the eastern and south-central U.S., with isolated flash flooding possible from the Northeast to the southern Plains.10 The National Weather Service (NWS) is also tracking monsoonal moisture that could trigger scattered thunderstorms and isolated flash flooding in the Southwest.11

Wildfire Updates

According to the National Interagency Fire Center (NIFC), there are currently 47 large fires burning across nine geographic areas nationwide as of yesterday, August 19.12 A total of 15,453 firefighters and support personnel are assigned to these incidents.13 In California, several large fires, including the Gifford Fire, Orleans Complex, and Rosa Fire, are reaching high levels of containment.14 In Newfoundland and Labrador, Canada, recent cooler temperatures and rain have greatly assisted fire suppression efforts.
