 Tropical Depression Mawar will continue to move inland across southeastern China and will spread heavy rain and flooding across the region through Monday.

Mawar made landfall as a tropical storm in southeastern China early Monday morning, local time. Landfall occured near Shanwei, between Hong Kong and Shantou.

The compact nature of Mawar should limit its most severe impacts to a small portion of southeastern China. However, hazards still exist to lives and property in Guangdong and neighboring Fujian province, as well as the Special Administrative Regions of Hong Kong and to a lesser degree Macao.
Soaking rain will also spread over parts of Taiwan during this time, leading to localized flash flooding.
“Given that this region has seen impacts from two tropical systems [Hato and Pakhar] in as many weeks, a third cyclone could more easily bring flooding and wind damage,” AccuWeather Meteorologist Adam Douty said.
As Mawar continues to weaken over land, the overall wind threat will continue to decrease. Destructive winds are not expected anymore but a few locally higher gusts can't be ruled out.
With the ground already saturated from Hato and Pakhar, trees may be more susceptible to being downed by gusty winds.
A total of 125-250 mm (5-10 inches) of rain in about as many hours may inundate a swath of the Guangdong coastline.
Flood-prone areas should anticipate rapidly rising water as the ground cannot handle much more rain and already swollen rivers and streams overflow their banks. Mudslides may also get triggered.

Travel is expected to be disrupted as the flooding rain threatens to close some roads and lead to flight delays and cancellations.
The worst impacts are expected to stay north of Hong Kong, but heavy rain can still occur in the city.
Due to the recent soaking rain from Hato and Pakhar, any significant rainfall can renew flash flooding or trigger more mudslides in and around the city.
Rain and wind across southeastern Guangdong is expected to wind down on Monday as Mawar presses farther inland, weakening to a tropical rainstorm.
However, flooding rain may still start the new week soaking far interior Guangdong along with southern Jiangxi and southern Hunan.
The heavy rain is expected to gradually lessen and become more scattered in nature by Tuesday from Jiangxi to Zhejiang and Fujian. Any flooding issues by this time would be isolated in nature.
