Tropical Cyclones

Tropical Cyclone 13E (Marie) is located about 705 miles southwest of San Diego, California

Tropical Cyclone 12E (Lowell) is located about 375 miles southwest of Lihue, Hawaii

Tropical Cyclone 22W (Krovanh) is located approximately 337 miles south-southeast of Sasebo, Japan

Northeast Pacific:  

Tropical Cyclone 13E (Marie) 

MARIE EXPECTED TO CONTINUE TO PRODUCE DANGEROUS BEACH CONDITIONS ALONG THE COAST OF BAJA CALIFORNIA AND SOUTHERN CALIFORNIA FOR THE NEXT COUPLE OF DAYS

According to the NHC advisory number 26…

Marie is moving toward the west-northwest near 7 mph (11 km/h). A turn to the northwest is forecast to occur over the next couple of days. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Steady weakening is expected for the next couple of days, and Marie is forecast to become a post-tropical remnant low on Wednesday. Tropical-storm-force winds extend outward up to 150 miles (240 km) from the center. The estimated minimum central pressure is 988 mb (29.18 inches).

HAZARDS AFFECTING LAND

SURF: Swells generated by Marie will continue to affect portions of the coast of the Baja California Peninsula and southern California for the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions.

Tropical Cyclone 12E (Lowell) 

TROPICAL STORM WATCH ISSUED FOR OAHU WITH LOWELL

According to the NHC advisory number 46…

Lowell is moving toward the north-northeast near 14 mph (22 km/h). A north- northeastward to northward motion at a faster forward speed is forecast through Tuesday. On the forecast track, the core of Lowell is expected to near or just west of Niihau tonight and early Tuesday. Lowell is then forecast to turn toward the northwest and slow down by early Wednesday after passing the Hawaiian Islands. Maximum sustained winds remain near 115 mph (185 km/h) with higher gusts. Lowell is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Gradual weakening is expected through Tuesday. However, Lowell is forecast to remain a hurricane as it passes near the Hawaiian Islands. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 950 mb (28.06 inches).

HAZARDS AFFECTING LAND 

WIND: Hurricane conditions are expected in Kauai County beginning this afternoon or evening. Wind speeds atop and on the windward and leeward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds. Tropical storm conditions are possible on Oahu beginning this afternoon.

Hurricane conditions are expected in the Papahanaumokuakea Marine National Monument between Nihoa and French Frigate Shoals tonight, with tropical storm conditions beginning this afternoon.

RAINFALL: Hurricane Lowell is expected to produce additional rainfall totals of 6 to 10 inches for Kauai, with maximum totals of 16 inches possible. For the Big Island, 4 to 8 inches of rain is expected with isolated totals of 12 inches possible. For Oahu and Maui county, 4 to 8 inches of rain is expected with isolated totals of 10 inches possible. This rainfall may produce significant flash flooding and mudslides, especially across Kauai county and portions of the Big Island.

STORM SURGE: The combination of storm surge and tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide…

Kauai County…2-4 ft, with the highest expected values along the south coast of Kauai and the island of Niihau
Oahu…Up to 1 ft

The deepest water will occur along the immediate coast near and to the right of the center, where the surge will be accompanied by large and destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.

TORNADOES: Several tornadoes are possible near Kauai and Niihau this afternoon through tonight. A few tornadoes are also possible across the remainder of the Hawaiian Islands.

SURF: Swells from Lowell are likely to cause life-threatening surf and rip current conditions during the next several days across many of the Hawaiian islands.

Tropical Cyclone 22W (Krovanh)

According to the JTWC warning number 26…sustained winds were 30 knots with gusts to 40 knots

Animated enhanced infrared (eir) satellite imagery depicts tropical depression 22W (Krovanh) with a partially exposed low-level circulation center (llcc) and flaring convection displaced to the northwest of the center. The convection is clearly being sheared to the northwest, which is caused by moderate to high southeasterly shear acting on the system. A dry and stable air mass to the northwest can be seen wrapping into the vortex, indicated by the field of stratocumulus clouds in the vicinity of Kyushu. A 071157z ascat scatterometer pass revealed a defined center with 30 knot winds confined to the eastern semicircle.

Environmental analysis indicates that 22W remains within a marginal environment, characterized by moderate poleward outflow aloft, 20-25 kts southeasterly vertical wind shear, extensive dry air entrainment, and warm (28-29 c) sea surface temperatures.

TD 22W is forecast to track nearly due north, along the western periphery of the str to the east through  24 hours. Following 24 hours, the system is expected to turn northeastward as it rounds the steering ridge axis. 22W is forecast to then skirt the southern coast of Japan, near the Shikoku and Kansai regions around 36 hours. Just after tau 36, the system will interact with a developing frontal boundary draped across Honshu. This will likely cause 22W to stretch and move unpredictably as the vortex washes out over Japan.

In terms of intensity, 22W is forecast to maintain its current intensity of 30 kts through 24 hours under the effects of the marginal environment. Dry air entrainment and southerly shear is expected to worsen through this time, however, the poleward outflow channel will improve. After 24 hours, southwesterly shear will significantly increase, causing 22W to weaken just before making landfall in Japan. The shallow vortex will then rapidly erode and stretch over the mountainous terrain with dissipation forecast to occur by 48 hours.
