Post-Songkran storms have finally hit Bangkok, causing slight damage and flooding in some areas.
The situation was worse upcountry where strong winds and downpours continued to inflict havoc on local residents.
The latest warning issued by the Meteorological Department on Tuesday said rain and wind will persist in the capital and some other 30 provinces - mainly in the northern, northeastern and eastern regions - at least until Wednesday.
More than half of Bangkok should brace for more rain, it added.
Traffic police reported the collapse of four electricity poles in Lat Krabang district in Bangkok due to gusty winds on Tuesday morning.
City Hall reported rain in some central and the northern and eastern parts of the capital. Min Buri suffered most, with 44.5 millimetres of rain, it added.
Flooding was reported on the outskirts of Bangkok including Khlong Luang district in Pathum Thani and Bang Bua Thong district in Nonthburi.

The situation is worse, however, in other provinces including Phitsanulok and Nakhon Ratchasima.
Gusty winds and heavy rain buffeted Wat Bot district in Phitsanulok for about 30 minutes from 4.30am, toppling several trees and damaging more than 10 houses.
Boonting Ruennoi of Ban Klong Pet said she saw parts of her roof blown more than 20 metres away, forcing her and her two daughters to find cover while they watched the interior of her house being damaged.
Flooding was also reported by rescue volunteers in Si Khieu district in Nakhon Ratchasima and Lam Sonthi district in Lop Buri.
An update from the Disaster Prevention and Mitigation Department on Tuesday showed about 1,500 houses in 24 provinces had been damaged by the turbulent weather conditions since Friday.
