THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 15.1S 98.6E IS NOW LOCATED NEAR 16.8S 99.0E, APPROXIMATELY 300 NM SOUTH-SOUTHEAST OF COCOS ISLAND. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS A FULLY EXPOSED AND ELONGATED LOW LEVEL CIRCULATION CENTER (LLCC) WITH CURVED CONVECTIVE BANDING ALONG THE EASTERN PERIPHERY. A 161255Z SSMIS 91GHZ MICROWAVE IMAGE FURTHER SHOWS THE BROAD AND ELONGATED LLCC WITH LIMITED CONVECTIVE BANDING DISPLACED TO THE EAST. AN OLDER 160337Z SCATTEROMETER PASS REVEALS AN ELONGATED LLCC WITH 20 KNOT WINDS WITHIN THE CIRCULATION AND STRONGER GRADIENT WINDS TO THE SOUTH. UPPER LEVEL ANALYSIS CONTINUES TO SHOW A MODERATE ENVIRONMENT WITH A SHORTWAVE TROUGH JUST WEST OF THE DISTURBANCE PRODUCING CONVERGENCE ALOFT WITH 15-20 KNOT VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. DUE TO THE IMPACTS OF THE SHORTWAVE TROUGH, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.

Hazard Highlights

Wildfires in Russia; Update on Flooding in Chile

Fires Rage through Southern Siberia

041515

PDC Global Hazards Atlas, centered on Siberia, Russia, displaying PDC Active Hazards, Potential Wildfire (Hotspots), and Population Density (LANDSCAN) layers.

As of Monday, April 13, wildfires in the Khakassia and Chita regions of Siberia had claimed the lives of 26 people (ReliefWeb). Fires in the Khakassia region affected more than 30 villages, leaving an estimated 5,000 people homeless. Reports indicate that 900 people sought medical attention, with 77 of them requiring hospitalization. Substantial livestock losses have also been reported.

Authorities are continuing investigations into the cause of the fires, though the combination of human carelessness, strong winds, and warm temperatures has been suspected.

Response Operations Continue Following Heavy Rainfall in Northern Chile

PDC Global Hazards Atlas, centered on Chile, displaying PDC Integrated Active Hazards and rainfall observations for the past five days.

In late March, heavy rainfall, flash floods, and mudslides devastated the Antofagasta, Atacama, and Coquimbo regions (NASA). According to meteorologists, though the recorded rainfall in the region was not extraordinary (barely exceeding 2 inches) the effect was disastrous in one of the driest regions of the world. As of April 12, reports indicate that more than 164,000 people have been affected and more than 8,000 homes have been destroyed or deemed uninhabitable (ReliefWeb/OCHA).

UN OCHA reports that response capacity in Chile has been stretched thin due to ongoing emergencies in the southern part of the country (read previous Hazard Highlights on Chile’s Wildfires and Villarica Volcano).

Current Hazard Warnings

Drought: United States (Western), Namibia

Biomedical: West Africa

Avalanche: United States (Utah)

Severe Weather: Canada (Manitoba), United States (Western), Chile, Paraguay

Wildfire: Russia (Siberia)

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.2S 98.0E IS NOW LOCATED NEAR 15.1S 98.6E, APPROXIMATELY 200 NM SOUTH-SOUTHEAST OF COCOS ISLAND. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A BROAD, BUT STILL DEFINED LOW LEVEL CIRCULATION CENTER (LLCC) WITH DISORGANIZED FLARING CONVECTION. A 151308Z SSMIS 91GHZ MICROWAVE IMAGE SHOWS FRAGMENTED, CONVECTIVE BANDING ALONG THE EASTERN PERIPHERY WRAPPING INTO A POORLY DEFINED LLCC. RECENT SCATTEROMETER DATA FURTHER DEPICTS A BROAD AND ELONGATED LLCC WITH 20-25 KNOT WINDS ALONG THE NORTHERN AND SOUTHERN OUTER PERIPHERIES. UPPER LEVEL ANALYSIS CONTINUES TO SHOW A MODERATE ENVIRONMENT WITH A SHORTWAVE TROUGH JUST WEST OF THE DISTURBANCE PRODUCING CONVERGENCE ALOFT WITH 20 KNOTS OF VERTICAL WIND SHEAR, PROHIBITING ORGANIZED CONVECTION. BASED ON DYNAMIC MODELS, THIS UPPER LEVEL TROUGH IS FORECAST TO PERSIST OVER THE SYSTEM FOR THE NEXT COUPLE DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. DUE TO DETRIMENTAL IMPACTS OF THE SHORTWAVE TROUGH, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 15.1S 96.9E IS NOW LOCATED NEAR 14.2S 98.0E, APPROXIMATELY 140 NM SOUTH-SOUTHEAST OF THE COCOS ISLANDS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A BROAD, DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH POORLY-ORGANIZED, FLARING DEEP CONVECTION. A 141027Z AMSU-B 89GHZ IMAGE DEPICTS FRAGMENTED, CONVECTIVE BANDING WRAPPING INTO A WEAKLY-DEFINED LLCC. SURFACE OBSERVATIONS FROM THE COCOS ISLANDS INDICATE NORTHWESTERLY WINDS AT 15 TO 20 KNOTS WITH SLP NEAR 1008MB. UPPER-LEVEL ANALYSIS INDICATES THAT THE LLCC IS LOCATED WITHIN A MARGINAL ENVIRONMENT ON THE NORTHERN EDGE OF A DEEP SHORTWAVE TROUGH, WHICH IS INHIBITING CONVECTIVE DEVELOPMENT. BASED ON THE DYNAMIC MODELS, THIS UPPER-LEVEL TROUGH IS FORECAST TO PERSIST OVER THE SYSTEM FOR AT LEAST A COUPLE DAYS, THEREFORE, SIGNIFICANT DEVELOPMENT IS UNLIKELY DURING THIS TIME FRAME. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
