On the 25th a depression with slight or moderate gradients seems to have been central over the Formosa Channel and SE coast of China. On the 26th the barometer had risen generally around the Channel, the lowest pressure lying near its northern entrance. On the 27th the weather at Nagasaki appears to have been influenced by a depression to the southward.
On the 28th at 4.25 p. "A depression appears to be situated to the WNW of Bolinao." On the 29th at 10.45 a. "The depression seems to be increasing in intensity but it apparently occupies' much the same position as yesterday.' Black South Cone hoisted. At 11.0 a. Forecast:-"baro- meter falling: moderate NE and E breezes, probably increasing: squally and showery.
On the 30th at 11.15 a. "The shallow depression to the S of Hongkong appears to be moving slowly towards NW." At 11.20 a. Forecast Barometer unsteady: moderate or fresh E to SE winds: squally and showery."
On the 1st July at 9.35 a. Black South Cone lowered. At 11.0 a. "the depression seems to be approaching the neighbourhood of Hainan Straits." Forecast:-barometer rising: moderate SE to Swinds: squally and showery to fair."
Between the 26th and 28th a considerable increase of pressure took place over S China and gradients became favourable for NE winds which, in fact, spread to the southward into the N part of the China Sea between the 27th and 28th. This appears to have resulted in the formation of an clongated depression across the China Sea and N Luzon into the Pacific in about 18° Lat. on the 28th.
On the 29th a circular but shallow depression (IV.) was probably central in 1893, 115° at noon. The bark Fooling Suey, which was situated in 17° 12', 113° 55' at noon, experienced fresh NW breezes in the morning backing to SW and S at night, and accompanied by rainsqualls throughout. The barometer fell to 29.48 at 8 p. when the centre passed to the N of the vessel. The S.S. Derawongse was situated in 18° 34', 111° 45′ and steering for Hongkong. Very threatening squally weather was experienced with the wind at NW. At Hongkong (bar. 29.70) a moderate ENE breeze prevailed with wet squally weather.
On the 30th at noon the centre was situated in about 19°, 113°. The Foohng Suey had a fresh S breeze with rain (bar. 29.52) in 18° 42′, 114° 10′, the S.S. Hongkong a fresh NE breeze with rainsqualls (bar. 29.56) in 20° 34', 111° 24', while several vessels situated a little to the south of Hongkong had strong E breezes with rainsqualls.
On July 1st the centre of the shallow depression seems to have passed over, or very near Hoihow about 4 p. The S.S. Frejr, nearing Hoihow from the Eastward, had the barometer falling with fresh E breezes backing to N at noon. At 4 p. she had come to anchor in Hoihow and the lowest barometer reading, 29.45, was then registered, the wind being variable and squally. Later the barometer rose rapidly and a moderate SW breeze sprang up. The direction backed to SSE and increased to a strong breeze during the night.
On July 2nd the depression appears to have passed to the E and N of Haiphong where the barometer fell to 29.52 and NW breezes accompanied by rain prevailed.
At noon on the 29th another circular depression (V) formed in the same trough to the E of N Luzon, was in about 20°, 1244°?. It is seldom that two cyclones form in the same trough, but these were very small. At noon on the 30th it was in about 2340, 1244°, on the 1st July in 26°, 127° and on the 2nd in 30°, 130°. The S.S. Arroyo in 25°, 127° was in this typhoon on the 30th. It was broken up on the 2nd.
JULY.
Typhoon VI was encountered by the bark Fred. P. Litchfield in the Pacific. On the 18th it may have been in 15°, 142°, on the 19th in 16°, 139°, on the 20th in 18°, 136°, on the 21st in 19°, 133°, on the 22nd in 22o, 130°, on the 23rd in 25°, 128°1⁄2, on the 24th in 32° 30′, 129° 45', on the 25th in 37°, 139°. It blew very hard in Japan. Great damage was done in SW Japan.
On the 25th at 7 p. "A depression appears to be forming in the Northern part of the China Sea." On the 26th at 11.0 a. Forecast:-"barometer falling: moderate E and SE winds: showery." On the 27th at 10.55 a., "There appears to be a typhoon near Bashee Channel," Red Drum hoisted. At 11.5 a. Forecast: barometer falling: light or moderate winds, variable: fair to showery."
On the 28th at 6.30 a, Black Drum hoisted. At 8.30 a., "Typhoon SE of Hongkong apparently moving towards WNW. Strong NE to SE gale expected here." Gun fired one round. At 1.30 p.. Black South Cone hoisted. At 4.20 p., "Centre of typhoon SSW of Hongkong, moving towards the coast between Macao and Hoihow." At 6.50 p, Black Ball hoistedl.
On the 29th at 10.10 a., Black Ball lowered. At 10.55 a. Forecast:-"barometer rising strong S breezes, decreasing: wet and squally."
On the 25th July a trough-like slight depression was formed across the China Sea between 17° and 19° Lat. as a result of a considerable increase of pressure which had taken place over S China between the 24th and 25th. Between the 26th and 27th a cyclonic depression (VII) which was perhaps central in 18°, 118° at noon on the latter day, may have been formed in the eastern part of the trough; but in the absence of observation from S. Formosa or from vessels in the adjacent waters this is uncertain.
