Tropical Storm Erin Forecast to Become First Major Hurricane of 2025

Tropical Storm Erin has formed in the eastern Atlantic and is expected to become the first hurricane and potentially the first major hurricane of the 2025 Atlantic season. The National Hurricane Center is issuing advisories on the storm, which is currently located west-northwest of the Cabo Verde Islands and moving west. While it is too early to determine its exact long-term path, current models suggest a northward turn that could keep the main part of the storm north of the Caribbean islands and away from the US. However, locations in the Caribbean, Bermuda, the Bahamas, and the US East Coast are being urged to monitor its progress closely. The storm has already caused significant damage and loss of life in the Cabo Verde Islands due to torrential rain and flooding.

National Fire Activity at Preparedness Level 4

According to the National Interagency Fire Center (NIFC), national preparedness is at level 4 with 30 large uncontained fires across the country. Significant fire activity is noted in the Rocky Mountain and Great Basin areas, with several large fires threatening communities and infrastructure in Colorado and Utah. Wildfire conditions remain elevated across much of the western United States due to hot, dry weather and low humidity.

Heavy Rain and Flooding Recede in Milwaukee Area

The Milwaukee area is drying out after unofficial record-breaking rain over the weekend caused significant flooding, washing out roads and leaving thousands without power. While flood warnings continue in some areas, the National Weather Service does not expect a repeat of the prolonged deluge.

Heat Wave and Monsoon Moisture for the West

A high-pressure system is building in the Great Basin, which will push temperatures into the triple digits by mid-week. This system is also expected to bring a pulse of monsoon moisture, leading to a slight chance of rain. However, dry lightning and outflow winds are also possible on the first day of rain chances.
