Three Tropical Cyclones Active in the Pacific; Flooding in Myanmar
Guam and the Northern Mariana Islands (collectively known as The Marianas) remain on watch, as Typhoon Chan-hom continues its approach to the islands (NWS Guam). Chan-hom is located (as of 1800 UTC on July 2) approximately 294 nautical miles southeast of Guam, with maximum sustained wind speeds of 65 knots (75 miles per hour) (JTWC). Typhoon Chan-hom is expected to intensify over the next couple of days, bringing heavy rain, strong winds, and dangerous surf conditions as it passes through The Marianas. Read more about potential impacts in this PDC Update.
Earlier this year, Typhoon Dolphin impacted The Marianas, passing between Guam and Rota.
Also active in the Pacific are Tropical Cyclones Raquel and Linfa. TC Raquel is located approximately 823 nautical miles east-northeast of Port Moresby, Papua New Guinea, with maximum sustained winds at 35 knots (40 miles per hour) (JTWC). TC Linfa is located 409 nautical miles east-northeast of Manila, Philippines, with maximum sustained winds at 40 knots (46 miles per hour) (JTWC).
RVA Country Profile: Myanmar
The Southwest Monsoon, which marks the start of Myanmar’s rainy season, has triggered flooding in several states and regions, affecting an estimated 13,000 people (ReliefWeb/AHA Centre). Reports indicate that Rahkine State has been the most affected by the recent flooding. With more rain forecast over the next few days, the PDC Global Risk and Vulnerability Index is useful for assessing the country’s unique combination of multi-hazard exposure, vulnerability, and coping capacity via PDC’s Multi-Hazard Risk Index.

- Heavy rainfall continues to impact areas of India. In Upper Assam, new flooding on June 29 has affected more than 5,500 people in 20 villages throughout the Sonitpur, Lahimpur and Dehmaji districts (ECHO). Heavy rainfall also triggered landslides in the Darjeeling district of West Bengal, with reports (from July 1) indicating that overnight, more than 100 homes in the towns of Mirik and Kalimpong had been washed away (ReliefWeb).
- Canada has seen an early start to the 2015 fire season, with reports of wildfire outbreaks beginning in late May due in part to a combination of lightning, parched forests, warm temperatures, and strong winds (NASA). According to reports, as of July 2, there are 116 active fires in Saskatchewan. So far this season, there have been 537 wildfires, up from 192 reported last year (Govt. of Saskatchewan). At the time of this report, there are 53 active fires of note in British Columbia, and reports out of Alberta indicate that this season is the “worst in five years” (BC Wildfire Service, NASA).
