Flossie weakens to a tropical depression, continues moving toward Hawaii

Tropical Storm "Flossie" weakened to a tropical depression at 03:00 UTC on August 5, 2019, and continued moving closer to Hawaii.

At the time, Flossie's center was located 565 km (350 miles) E of Hilo and 680 km (425 miles) ESE of Hana, Hawaii. Maximum sustained winds were 55 km/h (35 mph). The system was moving W at 20 km/h (13 mph) with minimum central pressure of 1 009 hPa.

This general motion is expected to continue into early Monday (HST), with a turn toward the WNW forecast late Monday and Tuesday, August 6. Weakening is forecast during the next 48 hours, and the system is expected to weaken to a post-tropical remnant low Monday night as it moves near or over the main Hawaiian Islands (Monday and Tuesday). 

Swells generated by Flossie will affect portions of the main Hawaiian Islands during the next couple of days, producing dangerous surf conditions through late Monday, mainly along east and southeast facing shores, NHC warns.

Moisture associated with Flossie will spread over portions of the main Hawaiian Islands on Monday, bringing the potential for heavy rainfall. Total rainfall amounts of 25 – 100 mm (1 to 4 inches) are expected, with localized higher amounts.
