The S-like shapes represent storm positions. The orange ones show Conson during times when the winds were (or are forecast to be) over 117 kilometers per hour, while the green ones are positions with maximum winds of 63 to 117 kilometers per hour.

On July 12, at 11 a.m. Hawaii Standard Time (2100 UTC), Tropical Cyclone Conson (03) was a typhoon in the West Pacific, meaning it had winds of at least 117 kilometers (74 miles) per hour. Joint Typhoon Warning Center’s warning (JTWC adv06) forecast a decrease in strength for Conson before making landfall in the Philippines, Tuesday afternoon (local time), July 13.

The system crossed over Manila (Luzon Island, Philippines) as a Tropical Storm. Leaving at least a few dozen people dead in the capital city. The decrease in strength continued as Conson moved over land, but maintained tropical storm strength. Leaving the Philippines, it proceeded into the South China Sea, where it continued for 12 or more hours to maintain its status as a tropical storm (winds of at least 63 KPH/about 38 mph). Then the storm increased in intensity over the warm water.

By the time of the 11 a.m. HST (2100 UTC), July 15th, advisory, the storm had regained Typhoon strength. At this time, the storm’s forecast track is moving slightly south. Whereas, Conson was forecast to make landfall on the Asian mainland at Hong Kong earlier, current models are suggesting Hanoi and northern Vietnam are more likely.

If currently observed trends persist, Conson could grow stronger, bringing destructive winds and rain to Vietnam, which could result severe flooding, landslides and flash floods.
