Australia Impacted by Severe Tropical Cyclone, Second to Follow; Heavy Rainfall in Honduras May Increase Flood Risk
Lam and Marcia Intensify on Australia Approach
Tropical Cyclones Lam and Marcia formed in waters off Australia this week and dramatically intensified as they approached the continent’s Northern Territory and Queensland coasts (Reuters, ECHO). Lam made landfall early Friday morning (local time) as a Category 4 storm on Australia’s tropical cyclone intensity scale, and is weakening as it moves inland with maximum sustained winds at 130 kilometers (approximately 81 miles) per hour (BOM Advisory #62). Marcia, located approximately 379 nautical miles north-northwest of Brisbane as of 2100 UTC, is forecast to make landfall Friday evening (local time) (JTWC Warning #5, BOM Advisory #27). Sustained wind speeds at 205 kilometers (approximately 127 miles) per hour currently place Marcia as a Category 5 storm on Australia’s tropical cyclone intensity scale. In addition to destructive winds, officials warn of potentially damaging waves and dangerous flooding as the two storms impact coastal areas.
Heavy Rain Headed to Honduras
A break in dry weather could be on the way for parts of Central America, as moderate to heavy rainfall is forecast for northern Honduras and areas of Nicaragua and Costa Rica (CPC). Increased rainfall should alleviate moisture deficits seen over the past month, though there is an increased risk of flooding and landslides.
